Question 4
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?

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)
$2\times 1+2(1\times 1.5+1.5\times 2)=2+2(1.5+3.0)=2+9.0=11m^2$
Hence required surface area of cabinet is $11m^2$
