Question

Find the surface area of a cuboid whose length, breadth and height are $15cm,12cm$ and $10cm$ respectively.

Answer 1

Given, Length of the cuboid $\left(l\right)=15cm$
Breadth of the cuboid $\left(b\right)=12cm$
Height of the cuboid $\left(h\right)=10cm$

Surface area of a cuboid $=2(lb+bh+hl)$
$=2(15\times 12+12\times 10+10\times 15)c{m}^2$
$=2(180+120+150)c{m}^2$
$=2\left(450\right)c{m}^2$
$=900c{m}^2$
