Answer 1

$\huge\mathcal\pink{ANSWER:-}$

Given: =Area= 9.375m?

=>22.5cm x 10cm x 7.5cem =1x bxh

=Total surface of cuboid (brick) = 2(Ib + bh + lh)

=>2(22.5 x 10+ 10 x 7.5 + 22.5 x 7.5) cm?

= 2 x 468.75 = 937.5 cm?

= Area that can be painted by part of container = 93750 cm?

=>Let x number of bricks will be used.

= Area = 937.5 x cm^2

=> x = 93750 / 937.5
