Question

What is the surface area of this figure
A rectangular prism with a height of 4 cm with a width of 5 cm and length of 8 cm

Answer 1

To find the surface area of a rectangular prism, we need to add up the areas of all its faces.

The formula for the surface area of a rectangular prism is:
Surface Area = 2lw + 2lh + 2wh

Given:
Length (l) = 8 cm
Width (w) = 5 cm
Height (h) = 4 cm

Substitute the given values into the formula:
Surface Area = 2(8)(5) + 2(8)(4) + 2(5)(4)
Surface Area = 80 + 64 + 40
Surface Area = 184 cm²

Therefore, the surface area of the rectangular prism is 184 square centimeters.
