Oscar is giving his mother a new acquarium in the shape of a rectuangular prism. He is going to wrap it in colorful wrapping paper. He know that he needs exactly 2,948 square inches of paper to wrap the aquarium. If the acuqarium is 40 inches long and 18 inches wide, what is the height of the aquariaum?
a) 13 inches
b) 14 inches
c) 15 inches
d) 16 inches
ignoring any overlap needed for wrapping
2lw + 2lh + 2wh = total area
2(40)(18) + 2(40)h + 2(18)h = 2948
116h = 1508
h = 13
is the answer 13
Are these numbers correct?
