Answer:
The height = 4 m answer (B)
Step-by-step explanation:
∵ The volume of any prism = base area × height
∵ The base is a right angle Δ with 3 and 5
∴ Area the base = 1/2 × 3 × 5 = 7.5 m²
∵ the volume of it = 30 m³
∴ 30 = 7.5 × height
∴ The height = 30 ÷ 7.5 = 4 m
Answer:
B. 4 m
Step-by-step explanation:
The volume of a right prism is given by
V = Bh
Where B is the area of the base and h is the height
B = 1/2 bh where b is 3 and h =5
B = 1/2 (3) (5)
= 7.5
V= Bh
30 = 7.5 *h
Divide by 7.5 on each side
30/7.5= 7.5 /7.5 h
4 =h
The height is 4 m
