Question

What is the volume of the figure below if a = 9 units and b = 7 units?

Answer 1

1,012.5 cubic units

Explanation:

Vcube = s3

= (9 units)3

= 729 cubic units

Vtri. prism = (bhbase ÷ 2) • hprism

= (9 units • 7 units ÷ 2) • 9 units

= (31.5 square units) • 9 units

= 283.5 cubic units

Then, add the volumes.

729 cubic units + 283.5 cubic units = 1,012.5 cubic units

Answer 2

If the figure is a cylinder, the volume is about 452.39. I hope I helped!
