Juanita covered the outside of a gift box shaped like a rectangular prism with paper. The box is 3.2 feet long, 2.1 feet wide, and 2.7 feet high. What is the total surface area of this box?

Sagot :

formula: A=2(wl+hl+hw)
= 2(2.1x3.2 + 2.7x3.2 + 2.7x2.1)
=2(6.75+8.64+5.67)
=2(21.06)
= 42.12 ANSWER
