The wall

We have to build a cuboid wall with dimensions base 30 cm and 45 cm and height 3.25 meters. Calculate how many we need bricks if we spend 400 pieces of bricks to 1 m3 of wall?

Correct result:

n =  175.5


n=0.30 0.45 3.25 400=3512=175.5n=0.30 \cdot \ 0.45 \cdot \ 3.25 \cdot \ 400=\dfrac{ 351 }{ 2 }=175.5

We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
