Question

What is the surface area of this composite solid?
Enter your answer in the box.
_m^2

Answer 1

2,100
`m^(2)`

Explanation:

Volume of the prism = b · h

Volume of the prism = 180 · 9

Volume of the prism = 1,620

Volume of the pyramid = b · h/3

Volume of the pyramid = 180 · 8/3

Volume of the pyramid = 480

Volume of the composite solid = 2,100
`m^(2)`
