Answer 2

Answer:

⇒Area=9.375m2

⇒22.5cm×10cm×7.5cm=l×b×h

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

⇒2(22.5×10+10×7.5+22.5×7.5) cm2

=2×468.75=937.5 cm2

⇒Area that can be painted by part of container =93750 cm2

⇒Let x number of bricks will be used.

⇒Area =937.5×x cm2

⇒x=937.593750

⇒x=100
