Answer:

10 in³

Explanation:

given:

square box = 4 in²,  length = 16 in

bar diameter = 2 in,   length = 16 in

box volume (in solid) = 4 in² * 16 in = 64 in³

bar volume = pi * d² / 4 = 3.14 * 2² / 4 *  16 in = 50.24 in³

Volume of slotted box = 64 - 50 = 10 in³

Answer:

The Answer is 205.76

Explanation:

4x4x16=256= Volume of the box

3.14x1^2x16= 50.24= Volume of the cycylinder

256-50.24=205.76
