Question

a wall 15m long, 30cm wide and 4 m high is made of bricks, each measuring 22cm×12.5cm×7.5cm. ​

Answer 1

CONVERT M IN CM

WE WILL DO LENGTH X BREATH X HEIGHT=15000 x 30 x 4000 = 6300,000,000

THEN AGAIN LENGTH X BREATH X HEIGHT= 22 x 12.5 x 7.5=2062.5

THEN SUBTRACT

6300,000,000- 2062.5=6299.997,837.5
