Question

Find the volume of the composite solid

Answer 1

Answer:

253.5 ft³

Step-by-step explanation:

Volume of a pyramid = $\frac{1}{3}$× base area × height

Volume of a prism = base area × height

Volume of the pyramid

= $\frac{1}{3}$× (6×6.5÷2) × 9

= $\frac{1}{3}$× 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

Answer 2

Answer:

A

Step-by-step 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
