The total surface area in m2 of a cuboid with dimensions of 26m, 14m and 6.5m

Question

The total surface area in $m^{2}$ of a cuboid with dimensions of 26m, 14m and 6.5m respectively is ___ m $^{2}$ .

Options:

Answer: Option A
:

Total Surface Area = 2( l x b + b x h + h x l)
= 2(26 x 14 + 14 x 6.5 + 6.5 x 26)
= 2(364 + 91 + 169
$= 1248 m^{2}$
