Surface area of rectangular prisms QuickChek math 6B
To find the surface area of a rectangular prism, you need to add up the areas of all six sides.
The formula for the surface area of a rectangular prism is:
Surface Area = 2lw + 2lh + 2wh
Where:
l = length
w = width
h = height
For example, if the length of the rectangular prism is 5 cm, the width is 3 cm, and the height is 4 cm, the surface area would be:
Surface Area = 2(5)(3) + 2(5)(4) + 2(3)(4)
Surface Area = 30 + 40 + 24
Surface Area = 94 square cm
Therefore, the surface area of the rectangular prism is 94 square cm.
