Hope it helps you

Step-by-step explanation:

To Find

TSA of brick = 2(lb+bh+lh)

l=15 ; b= 10 ; h=10

$tsa \: of \: brick \: =2 ((15 \times 10) + (10 \times 10) + (15 \times 10)) \\ = 2(150 + 100 + 150) \\ = 2(400) \\ = 800cm {}^{2}$

Area can be painted with 1 container of paint =8 sq.m

Area can be painted with 5 container of paint=8×5

=40 sq.m

40 sq.m= 4000sq.cm

$Area \: can \: be \: painted \: with \: 5 \: container \: of paint= \frac{Area \: can \: be \: painted \: with \: 5 \: container \: of \: paint}{tsa \: of \: 1 \: brick} \\ = \frac{4000}{800} \\ = 5 \: bricks$
