Kissing needs to paint the top and side of rectangular prism prism has a length of 25 mm in with a 15 mm in height of 9 mm how much paint does she need to come the top and sides

Therefore she needs 1095 mm²to paint the top and sides.

Step-by-step explanation:

Given that Kissing needs to paint the top and side of rectangular prism has a length = 25 mm ,width= 15 mm and height = 9 mm.

The rectangular prism has 6 face.

The floor of the prism is not painted.

Only sides and top is painted.

The surface area of the sides and top is

= 2(length + breadth)×height+ (length × breadth)

=[2(25+15)×9 +(25×15)] mm²

=1095 mm²

Therefore she needs 1095 mm²to paint the top and sides.
