Question

Rachel wants to paint her cupboard. The length of the cupboard is 2.5 meters, its width is 1 meter, and its height is 2 meters. How much area will she need to paint if she paints both the bases and all the lateral faces?

Answer 1

the answer is 10 m2

Explanation:

Answer 2

I think Rachel need to paint 19 meters.

We need to find the L x W, L x H, and W x H.

It appears to be a rectangular prism.

L x W = 2.5 x 1 = 2.5
L x H = 2.5 x 2 = 5
W x H = 1 x 2 = 2

2.5
5
+2
____
9.5 x 2 because the figure has 6 sides not 3 so the answer is :

9.5 x 2 = 19 meters

P.S. You just had to find the surface area of the rectangular prism ;)
