Question

Meghna painted the outside of the cabinet of measure 2 m × 3 m × 2.5 m. How much surface area did she cover if she painted all except the bottom of the cabinet and back side?

Answer 1

Answer:

Since we have given that

Length = 2 m

Width = 3 m

Height = 2.5 m

So, we need to paint it except the bottom and back side.

So, Surface area would be

\begin{gathered}lb+bh+2lb\\\\=2\times 3+3\times 2.5+2\times 2.5\times 2\\\\=6+7.5+10\\\\=23.5\ m^2\end{gathered}

lb+bh+2lb

=2×3+3×2.5+2×2.5×2

=6+7.5+10

=23.5 m
