Question

please solve it with right answer and process..​

Answer 1

Step-by-step explanation:

Volume of wall : 980 m³

volume of bricks : 0.005 m³

according to question -

1/10 vol of wall = vol of entrance

1/10 × 980 = vol. of entrance

98 m³ = vol. of entrance

vol. of wall to be built= vol. of wall - vol of.

entrance

= 980 - 98

= 882 m³

no. of bricks = vol. of wall ÷ vol. of bricks

= 882 ÷ 0.005

= 176400
