Question

Ms. Benson is making a jewelry box using 2 identical squares of wood and 4 identical rectangular pieces of wood, as shown below.

What is the surface area of the jewelry box in square inches (sq. in)?

Answer 1

Length of rectangles = 7 in.

Breadth of 4 rectangles = 3 x 4

= 12 in.

Side of squares = 3 in.

Area of 4 rectangles = length x breadth

= 7 x 12

= 84 sq. in.

Area of two squares = 2(side x side)

= 2(3 x 3)

= 18 sq. in.

Therefore, Surface area of the Jewellery box = 84 sq. in. + 18 sq. in.

= 102 sq. in.
