Find the surface area of the rectangular prism

Question

the length is 7cm
the width is 4cm
and the height is 2cm
what is top area of the rectangular prism
What is the bottom area of the rectangular prism
what is the right side of the rectangular prism
what is the left side of the rectangular prism
what is the front side of the rectangular prism
what is the area of the back of the rectangular prism

Answer 1

The formula to calculate the surface area of a rectangular prism is 2lw + 2lh + 2wh.

Given:
Length (l) = 7 cm
Width (w) = 4 cm
Height (h) = 2 cm

Surface Area:
= 2(7)(4) + 2(7)(2) + 2(4)(2)
= 56 + 28 + 16
= 100 cm²

Now, to find the specific areas:

Top Area:
= 7 * 4
= 28 cm²

Bottom Area:
= 7 * 4
= 28 cm²

Right Side:
= 7 * 2
= 14 cm²

Left Side:
= 7 * 2
= 14 cm²

Front Side:
= 4 * 2
= 8 cm²

Back Side:
= 4 * 2
= 8 cm²
