Question

Find the
volume of the
composite solid

Answer 1

A

Explanation:

the base is 19.5 feet squared

(6 * 6.5 / 2)

multiplied by 10 gives you 195 feet cubed for the lower solid

19.5 * 9 / 3

gives you 58.5 feet cubed for the upper solid

just add both volumes together

Answer 2

253.5 ft³

Explanation:

Volume of a pyramid =
`(1)/(3)`× base area × height

Volume of a prism = base area × height

Volume of the pyramid

=
`(1)/(3)`× (6×6.5÷2) × 9

=
`(1)/(3)`× 19.5 × 9

= 58.5 ft³

Volume of the prism

= (6×6.5÷2) × 10

= 195 ft³

Volume of the solid

= 58.5 + 195

= 253.5 ft³
