Question

What is the surface area of this rectangular prism? 10 Points to the right answer! :D

Answer 1

`S.A=160cm^2`

Explanation:

The surface area of a rectangular prism is given by the formula;

`S.A=2(lw+lh+wh)`

From the diagram;

The length is
`l=10cm`.

The width is
`w=5cm`.

The height is
`h=2cm`.

Substitute these values into the formula to obtain;

`S.A=2(10*5+10*2+5*2)`

`S.A=2(50+20+10)`

`S.A=2(80)`

`S.A=160cm^2`
