Unit 6 - Surface Area And Volume For Rectangular Prisms

1. If a box has a length of 8 cm, a width of 20 and a heigt of 7 cm, what is the volume?

304

1120

1122

The volume of a box can be calculated by multiplying its length, width, and height. In this case, the length is 8 cm, the width is 20 cm, and the height is 7 cm. Multiplying these values together, we get 8 x 20 x 7 = 1120. Therefore, the volume of the box is 1120 cubic centimeters.

Explanation

The volume of a box can be calculated by multiplying its length, width, and height. In this case, the length is 8 cm, the width is 20 cm, and the height is 7 cm. Multiplying these values together, we get 8 x 20 x 7 = 1120. Therefore, the volume of the box is 1120 cubic centimeters.

2. Is the volume of 8*7*5 = 280?

True

False

The volume of a rectangular prism can be calculated by multiplying its length, width, and height. In this case, the length is 8 units, the width is 7 units, and the height is 5 units. Multiplying these values together gives us a volume of 280 cubic units. Therefore, the statement "The volume of 8*7*5 = 280" is true.

3. A box of milk has a length of 8 cm and a height of 5. The volume is 280. What is the width?

10

7

12

You need to divide the volume by the other dimensions to get the correct answer.
208 / 8 / 5

Explanation

You need to divide the volume by the other dimensions to get the correct answer.
