Question

Rukshar painted the outside of the cabinet of measure $1m\times 2m\times 1.5m.$ How much Surface area did she cover if she painted all except the bottom of the cabinet?

Answer 1

Here, Length of cabinet l = 2 m, Breadth of cabinet b= 1 m
And Height of cabinet h = 1.5 m
$\therefore$ Surface area of cabinet that has been painted $=lb+2(bh+hl)$
$=(2\times 1)+2(1\times 1.5+1.5\times 2)$
$=2+2(1.5+3.0)$
$=2+2\left(4.5\right)$
$=2+9$
$=11m^2$
Hence required surface area of cabinet is $11m^2$.
