Answer:
u = 10 ft
Explanation:
Volume of a rectangular prism = lwh
where:
- l = length
- w = width
- h = height
Given:
- Volume = 560 ft³
- width = 7 ft
- length = 8 ft
- height = u
Substitute the given values into the formula and solve for h:
⇒ 560 = 8 × 7 × u
⇒ 560 = 56u
⇒ 56u ÷ 56 = 560 ÷ 56
⇒ u = 10 ft
Therefore, the height of the prism is 10 ft.
