What is the formula for the surface area of a cube?

SA = 6s^2 (correct)

SA = 4s^2

SA = 3s^2

SA = 5s^2

What is the formula for the volume of a rectangular prism?

V = l + w + h

V = 2lw + 2lh + 2wh

V = lw + lh + wh

V = l × w × h (correct)

What is the formula for the surface area of a cylinder?

SA = 4πr(h + r)

SA = 3πr(h + r)

SA = 2πr(h + r) (correct)

SA = πr(h + r)
