Help with this question, please! I don't understand!!

Answer 1

A

Explanation:

The volume (V) of a pyramid is calculated using the formula

V =
`(1)/(3)` × area of base × height

note the height = 48 × 10 = 480 ( 48 storeys at 10 feet )

V =
`(1)/(3 )` × 571,536 × 480

= 91,445,760 ft³

[ 1 yd³ = 27 ft³ ], hence

V =
`(91445760)/(27)` = 3, 386, 880 yd³ → A
