Question

Surface area of a new cereal box with dimensions of
L=8 in
W=1.75in
H=12.125in

Answer 1

264.4375

Explanation:

Surface area of a box = 2(lw + lh + wh)

L = 8 , W = 1.75 and H = 12.125

==> plug in values

SA = 2((8)(1.75) + (8)(12.125) + (1.75)(12.125))

==> multiply values that are inside parenthesis together

SA = 2(14 + 97 + 21.21875)

==> add values inside of parenthesis

SA = 2(132.21875)

==> multiply 2 and 132.21875

SA = 264.4375in²
