Question

the paint in a certain container is sufficient to paint an area equal to 9.375 m. How
many bricks of dimensions 22.5 cm x 10 cm x 7.5 cm can be painted out of this
container?
al hoy has each edge 10 cm and another cuboidal box is 12.5 cm long. 10 cm​

Answer 1

Answer:

Length = 22.5

Breadth = 10 cm

Height = 7.5 cm

so , the area = 2(lb + bh + hl )

                     = 2 (22.5*10 + 10*7.5+22.5*7.5 )

                     = 2 ( 225 + 75 + 168.75 )

                      = 2 * 468.75

                    = 937.5 cm units

Therefore , Bricks = Area painted by a container / Area of a brick

                              = 9.375 * 10000 / 937.5

                              = 100 bricks
