Answer:
For Volume: 54ft^3
For Surface Area: D. 90ft^2
Step-by-step explanation:
Volume formula of rectangular prism: V = L * W * H
By replacing the variables with the given numbers we get the following:
V = 3ft * 3 ft * 6 ft
By multiplying, we get 54ft^3.
Surface Area formula of rectangular prism: SA = 2 (L*W + L*H + W*H)
By replacing the variables with the given numbers we get the following:
SA = 2 (3*3 + 3*6 + 3*6)
By multiplying, we get:
SA = 2 (9 + 18 + 18)
We add the numbers inside the parenthesis, then we multiply by two to get the following:
SA = 90 ft^2
