Answer:
So you need to find the surface area...
Explanation:
The length is 20, the width is 14, and the height is 10. It is a rectangular prism so it has six sides.
Two of the sides are l*w
Two of the sides are w*h
and two of the sides are l*h
This gives us equations of 2*(20*14), 2*(14*10), and 2*(20*10)
simplify that to 2*280, 2*140, and 2*200. Then you simplify that to,
560,280,and 400. Now simply add these numbers together to get.
1240.
So your answer is...
ANSWER: 1240 cubic units
