Question

Find the surface area of a cuboid whose

$\left(i\right)$ length$=10cm,$ breadth$=12cm,$ height$=14cm$

Answer 1

Given: Length of a cuboid $\left(l\right)=10cm$

Breadth of a cuboid $\left(b\right)=12cm$

Height of a cuboid $\left(h\right)=14cm$

We know that,

Surface area of cuboid $=2(lb+bh+hl)$

$=2(10\times 12+12\times 14+14\times 10)$

$=2(120+168+140)$

$=2\left(428\right)$

$=856c{m}^2$

Hence, the surface area of cuboid is $856c{m}^2.$
