Answer:
Step-by-step explanation:
total area of the paint in the container able to paint
surface area of a brick
surface area of a brick = 2(l.b+l.h+b.h)
= 2(11.5*10+11.5*6+10*6)
= 2(115+69+60)
= 2( 244)
= 488
no.of.bricks that can be painted=
total area of the paint in the container able to paint
surface area of a brick
convert m into cm :1464 *100 *100 = 14640000cm sq
no.of.bricks that can be painted= 14640000/488
= 30,000
