There is a box shaped like a rectangular prism. The base of the box measures 19 in by 7 in. The total surface area of the box is 1,202 square in. What is the height of the box?

Answer 1

SA=1202= 2(19)(7)+2(19h)+ 2(7h)

601= 19(7)+ 19h+7h

26h= 601- 133= 468

h= 468/26= 234/13= 18 inches in height

SA= 2(19x7 +18x7 +19x18)=2(133+126+342)= 2(601)=1202
