Question

A rectangular prism has dimensions of 2 cm by 2 cm by 5 cm. What is its surface area? Explain also and thanks if anyone answers my question!

Answer 1

The surface area is 48cm^2

Explanation:

Given

Dimension: 2cm by 2cm by 5cm

Shape: Rectangular Prism

Required

Determine its Surface Area (A)

This is calculated as thus:

`A = 2(lw + lh + hw)`

Where l, w and h are the dimensions of the given shape:

We can say:

`l = length = 2cm`

`w=width = 2cm`

`h=height=5cm`

So:

`A = 2(2 * 2 + 2 * 5 + 5 * 2)`

`A = 2(4 + 10 + 10)`

`A = 2(24)`

`A = 2 * 24`

`A = 48`

Hence, the surface area is 48cm^2
