Answer 1

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.

Answer 2

u = 10 ft

Explanation:

cuboid volume = w × h × l

width * hight * length

560 = 7 × 8 × u

u = 10 ft
