Question

Rukhsar painted the outside of the cabinet of measure 1 m &#xD7; 2 m &#xD7; 1.5 m. How much surface area did she cover if she painted all except the bottom of the cabinet.

Philoid · Accepted Answer

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

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

= 13 m²

Area of Bottom Surface = 1 x 2 = 2 m²

Hence, Area Covered by painting = 13 – 2 = 11 m²
