Sand path

How many m3 of sand is needed to fill the 1.5m wide path around a rectangular flowerbed of 8m and 14m if the sand layer is 6cm high?

Correct answer:

V =  4.5 m3

Step-by-step explanation:

s=1.5 m a=8 m b=14 m h=6 cm m=6:100  m=0.06 m  S1=(a+2 s) (b+2 s)=(8+2 1.5) (14+2 1.5)=187 m2 S2=a b=8 14=112 m2 S=S1S2=187112=75 m2  V=h S=0.06 75=4.5 m3
