Question

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

Answer 1

Answer:

$S.A=160cm^2$

Step-by-step 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;

$S.A=2(10\times5+10\times2+5\times2)$

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

$S.A=2(80)$

$S.A=160cm^2$
