Answer 2

$\bold\red{\underline{\underline{Answer:}}}$

4672$\bold{cm^{2}}$ of wood is to be painted.

$\bold\purple{Explanation}$

For getting area of wood which is to be painted from outside we have to find the total surface area of cuboidal piggy bank.

$\bold\orange{Given:}$

For cuboidal piggy bank,

Length (I) = 32cm

Breadth (b) = 28cm

Height (h) = 24cm

$\bold\pink{To \ find:}$

Area of the wood is to be painted.

$\bold\green{\underline{\underline{Solution}}}$

Total surface area of cuboidal piggy bank

=2(lb+bh+lh)

=2(32×28+28×24+32×24)

=4672$\bold{cm^{2}}$

Therefore,

$\bold\purple{4672cm^{2} \ of \ wood \ is \ to \ be \ painted.}$
