Answer:
(7) 1482 in³
(8) 216 yd³
Step-by-step explanation:
Formulas
Volume of prism
= base × height/length
Area of parallelogram
= base × height
Area of trapezium
= (upper base + lower base) × height ÷ 2
(7)
Area of the base = 19×6
= 114 in²
Length = 13 in
Volume = 144×13
= 1482 in³
(8)
Area of the base = (11+7)×12÷2
= 108 yd²
Length = 2 yd
Volume = 108×2
= 216 yd³
