$\huge {\mathbb{\blue{Hello!!}}}$

Step-by-step explanation:

Length of brick = 25cm

breadth of brick = 15 cm

height of brick = 10cm

volume of brick = length × breadth × height

= 25 cm × 15 cm × 10cm

= 3750 cm³

length of wall = 6m = 600 cm

breadth of wall = 0.5 m = 50cm

height of wall = 2.5 m = 250 cm

volume of wall = length × breadth × height

= 600 × 250 × 50 = 7500000 cm³

= 7500000/3750

= 750000/375

= 2000

hence, number of bricks = 2000

Answer 2

Answer:

2000 bricks

Step-by-step explanation:

Let us first find the area of a cuboid.

Since the dimensions of the bricks are in cm, let us convert everything into cm.

We get,

Length   = 600 cm

Breadth =  250 cm

Height   =  50 cm

Volume of a cuboid = length x breadth x height

So the volume of the wall = l x b x h

                                           = 600cm x 250cm x 50cm = 7500000cm³

Volume of 1 brick = l x b x h

                             = 25cm x 15cm x 10cm = 3750 cm³

To find the number of bricks required to build the wall = 7500000 ÷ 3750                                            

                                                                                           = 2000 bricks

Hope this helps !!
