Question

Explain how to find the surface area of rectangular prisms and cubes. What formulas can you use?

Answer 1

Answer:

surface area of rectangular prisms A=2(wl+hl+hw)

surface area of cubes A=$6a^{2}$

Step-by-step explanation:

Answer 2

Answer:

The total surface area of a rectangular prism or cube is equal to the sum of the areas of each side.

The area of each side is equal to its length multiplied by its width or A = L x W.

Since the areas of opposite sides are equal, multiple each side area by 2 to obtain the areas of opposite sides.

where:

L = length

W = width

H = height

total area = (2)(L)(W) + (2)(L)(H) + (2)(W)(H)

or simplified:

total area = 2[(L)(W) + (L)(H) + (W)(H)]
