What is the formula for the surface area of a rectangle?Note: h=height, l=length, w=width
-
3x lbh
-
Base x height
-
2lw +2wh + 2lh
Correct Answer
A. 2lw +2wh + 2lhExplanation
The formula for the surface area of a rectangle is 2lw + 2wh + 2lh. This formula accounts for all six sides of the rectangle: the two length sides, the two width sides, and the two height sides. By adding up the areas of each side, we can find the total surface area of the rectangle.Rate this question:

What is the surface area of the cyliner?
-
96
-
1005.31
-
2412.74
-
804.25
Correct Answer
A. 1005.31Explanation
The correct answer is 1005.31. To find the surface area of a cylinder, we need to calculate the sum of the areas of the two bases and the lateral surface area. The formula for the surface area of a cylinder is 2Ï€r^2 + 2Ï€rh, where r is the radius of the base and h is the height of the cylinder. Without further information given in the question, we cannot determine the exact values of r and h. Therefore, we cannot calculate the surface area of the cylinder and provide an explanation for the given answer.Rate this question:

What is is the total surface area of a triangular prism with the dimensions of 7cm X 15cm X 6cm?
-
357cm^2
-
49cm^2
-
630cm^2
Correct Answer
A. 357cm^2Explanation
The total surface area of a triangular prism can be calculated by finding the sum of the areas of all its faces. In this case, the triangular prism has two triangular faces and three rectangular faces. The area of each triangular face can be calculated using the formula 1/2 * base * height, where the base is 7cm and the height is 15cm. The area of each rectangular face can be calculated using the formula length * width, where the dimensions are given as 7cm X 15cm, 7cm X 6cm, and 15cm X 6cm. Adding up the areas of all the faces gives a total surface area of 357cm^2.Rate this question:

Which rectangular prism has a larger surface area?Prism A: Dimensions are 5 by 4 by 2Prism B: Dimensions are 6 by 3 by 2
-
Prism A
-
Prism B
-
They have the same Surface Area
Correct Answer
A. Prism AExplanation
Prism A has a larger surface area because the formula to calculate the surface area of a rectangular prism is 2lw + 2lh + 2wh. By plugging in the dimensions of Prism A (5, 4, and 2), we get 2(5)(4) + 2(5)(2) + 2(4)(2) = 40. By plugging in the dimensions of Prism B (6, 3, and 2), we get 2(6)(3) + 2(6)(2) + 2(3)(2) = 36. Therefore, Prism A has a larger surface area of 40 compared to Prism B's surface area of 36.Rate this question:
