What is the surface area of a rectangle? (Information on the bottom)

Question

The rectangle has a height of 10, A length of 4, And a width of four, And the base of the right triangle is a rectangle.

Answer 1

You don't really need the part with the rectangle:

The surface area of a rectangular prism is:

2ab + 2bc + 2ac

Make A = 10

B = 4

C = 4

You can set those as anything, it just makes doing the formula easier.

(2)(10)(4) + (2)(4)(4) + (2)(10)(4)

80 + 32 + 80

160 + 32

192 is the surface area.
