Question

3.

Mary has had the same jewelry box since she was 6 years old. It badly needs
a paint job! Find the total surface area of the box so that Mary can color her entire
jewelry box bright pink and make it look brand new. The height is 4.2 inches, the
width is 3.1 inches and the length is 7.5 inches. Round your answer to the nearest
square inch.

Answer 1

2(h × W) + 2(h × L) + 2(W × L)

2(4.2•3.1)=26.04
2(4.2•7.5)=63
2(3.1•7.5)=46.5
26.04+63+46.5=135.54 in
