Answer:
A. 176
Step-by-step explanation: First, to find the surface area to each triangle, you multiply the base times the height by 1/2. It is 28 for each triangle. Multiply that by 4, and you get 112. Then, the surface area of the square on bottom is 64. When added together, you get 176. No rounding needed. Hope it helped and is correct!
Answer:
15/10, 30/20, 60/40, 120/80, 240/160, 480/320
Step-by-step explanation:
The number of push-ups is 2/3 the amount of sit-ups, so the ratio of sit-ups to push-ups is 3:2.
The easy way to do this is to double both 15 and 10 so your answer will stay an equivalent ratio. You will always have a 3:2 ratio this way.

Question:
If all the edges of prism A are multiplied by 5 to create prism B. The volume of prism B will be __________ times the volume of prism A?
* 5
* 125
* 50
* 25
Answer:
* 5 times.
Step-by-step explanation:
Let us represent all the edges of prism A as = X
Prism B = All the edges of Prism A × 5
Prism B = X × 5
= 5X
Let's assume the prism is a cube
Volume of a Prism(cube) = L × W × H
Volume of Prism A = L × W × H
Volume of Prism B = 5 (L × W × H)
Therefore, The volume of prism B will be 5 times the volume of prism A
