# Rukhsar painted the outside of the cabinet of measure 1 m × 2 m × 1.5 m. How much surface area did she cover if she painted all except the bottom of the cabinet.

Answer :

Given,

length, l = 1 m

Breadth, b = 2 m

Height, h = 1.5 m

Surface Area of Cabinet = 2(lb + lh + bh)

= 2(1 x 2 + 1 x 1.5 + 1.5 x 2)

= 13 m^{2}

Area of Bottom Surface = lb = 1 x 2 = 2 m^{2}

Therefore,

Hence, Area Covered by painting = 13 – 2 = 11 m^{2}
