Answer:
Step-by-step explanation:
Volume = length * width * height
1) Volume = ( 7 * 3 * 7) + ( [7- 5) * 2 * 7)
= 147 + ( 2 *2 *7)
= 147 + 28
= 175 cubic ft
2) Volume = (6 * 3 *3 ) + ( 1 * 2 *3)
= 54 + 6
= 60 cubic ft
3) Volume = ( 3 * 4 * 7 ) + ( 7 * 4 * [6-4] )
= 84 + ( 7 * 4 * 2)
= 84 + 56
= 140 cubic ft
4) Volume = (3 * 4 * [6-4] ) + ( 12 * 4 * 4)
= (3* 4 * 2) + 192
= 24 + 192
= 216 cubic ft
