Question

The height, breadth and length of a cuboid are $5cm,9cm$ and $12cm$ respectively. Find the total surface area and the volume of cuboid.

Answer 1

GivenLength of cuboid ( 1$)=12cm$ Breadth $\left(b\right)=9cm$
and Height $\left(h\right)=5cm$
Total surface area of cuboid $=2(lb+bh+hl)$
$=2\left[\right(12\times 9)+(9\times 5)+(5\times 12\left)\right]$
$=2[108+45+60]$
$2\times 213=426{cm}^2$
Volume $=l\times b\times h$
$=12\times 9\times 5=540{cm}^3$
Hence, total surface area of cuboid $426{cm}^2$
And volume of the cuboid $540{cm}^3$
