Please help asap due very soon thank you so so much!!!

Answer 1

75.9 [in³].

Explanation:

1) the required volume can be caclulated according to the formula:

`V=(1)/(3) AB^2*SF, \ where \ AB-the \ side \ of \ the \ base, \ SF-height.`

2) in ΔSRF: RF=0.5*AB=3, SR=7, then

`SF=√(SR^2-RF^2)=√(40) [in].`

3) finally,

`V=(1)/(3) *36*√(40)=24√(10) \ or`

V≈75.9 [in³].
