Cross-section 5089

The brick pillar with a cross-section of 41x77 cm has a height of 3.25 m. Calculate:

(a) the volume of the pillar
b) the required number of bricks (if we need 400 pieces per 1 cubic meter)

Correct answer:

V =  1.026 m3
n =  411

Step-by-step explanation:

a=41/100=10041=0.41 m b=77/100=10077=0.77 m c=3.25 m V=a b c=0.41 0.77 3.25=1.026 m3
n=V 400=1.026 400=411
