Rukhsar 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.
Given: Rukhsar painted the outside of the cabinet of measure 1m $\times$ 2m $\times$ 1.5m
To find: How much the surface area did she cover if she painted all except the bottom of the cabinet.
Solution:
Surface area which is painted = Front area $+$ Back area $+$ Area of top $+$ Area of left side $+$ Area of right side
Front area = $ 2 \times 1.5 = 3$ m2
Back area = $2 \times 1.5 = 3$ m2
Area of top = $1 \times 2 = 2$ m2
Area of left side = $1 \times 1.5 = 1.5$ m2
Area of right side = $1 \times 1.5 = 1.5$ m2
Surface area which is painted = $3 + 3 + 2 + 1.5 + 1.5 = 6 + 2 + 3 = 11$ m2
Surface area which is painted = 11 m2
