Year 9 Measurement

1)
Area =

65 square m

62.3 square cm

63 square m

62.3 square m

The correct answer is 63 square m. This is because it is the only option that matches the given area of 65 square m. The other options, 62.3 square cm and 62.3 square m, do not match the given area.

Explanation

The correct answer is 63 square m. This is because it is the only option that matches the given area of 65 square m. The other options, 62.3 square cm and 62.3 square m, do not match the given area.

2) Complete the following 3500mL = _____ L

350L

35L

3.5L

0.35L

The given question asks to complete the equation by converting 3500mL to liters. To convert milliliters to liters, we divide by 1000. Therefore, 3500mL is equal to 3.5L.

Explanation

The given question asks to complete the equation by converting 3500mL to liters. To convert milliliters to liters, we divide by 1000. Therefore, 3500mL is equal to 3.5L.

3) Find the volume of a cube with side length of 4 cm

14 square cms

64 cubic cms

16 cubic cms

12 cubic cms

The volume of a cube is found by multiplying the length of one side by itself twice. In this case, the side length is given as 4 cm. So, the volume would be 4 cm * 4 cm * 4 cm = 64 cubic cm.

Explanation

The volume of a cube is found by multiplying the length of one side by itself twice. In this case, the side length is given as 4 cm. So, the volume would be 4 cm * 4 cm * 4 cm = 64 cubic cm.

4) An hectare is an area of 100m times 100m

True

False

An hectare is a unit of measurement for land area commonly used in agriculture and forestry. It is equivalent to 10,000 square meters or 100 meters by 100 meters. Therefore, the statement that an hectare is an area of 100m times 100m is correct.

Explanation

An hectare is a unit of measurement for land area commonly used in agriculture and forestry. It is equivalent to 10,000 square meters or 100 meters by 100 meters. Therefore, the statement that an hectare is an area of 100m times 100m is correct.

5) Find the area of the following trapezium

8.6 square metres

12.32 square metres

8.4 square metres

32.032 metres square

6) Find the Volume of the following prism

12 cms

48 square cms

12 cubic cms

48 cubic cms

The answer is 48 cubic cms because the volume of a prism is calculated by multiplying the area of the base by the height. In this case, the given measurements of 12 cms and 48 square cms are both dimensions of the base. Since the base is a square, the area can be calculated by squaring one of the dimensions, which gives us 48 square cms. Multiplying this area by the given height of 12 cms gives us a volume of 48 cubic cms.

Explanation

The answer is 48 cubic cms because the volume of a prism is calculated by multiplying the area of the base by the height. In this case, the given measurements of 12 cms and 48 square cms are both dimensions of the base. Since the base is a square, the area can be calculated by squaring one of the dimensions, which gives us 48 square cms. Multiplying this area by the given height of 12 cms gives us a volume of 48 cubic cms.

7) If 1000mL = 1 L then what does 1000 L equal?

The given question states that 1000mL is equal to 1 L. Since a kilolitre (KL) is equal to 1000 L, it can be concluded that 1000 L is equal to 1 KL. Therefore, the correct answer is 1 Kilolitre, KL, 1 KL, or 1 KiloLitre.

Explanation

The given question states that 1000mL is equal to 1 L. Since a kilolitre (KL) is equal to 1000 L, it can be concluded that 1000 L is equal to 1 KL. Therefore, the correct answer is 1 Kilolitre, KL, 1 KL, or 1 KiloLitre.
