Flower boxes

How many m2 of 10mm thick boards are needed to make 12 flower boxes? The dimensions of the box are 180,150 and 1500 mm.

Correct result:

x =  11.6592 m2

Solution:

h=10 mm n=12 a=180 mm b=150 mm c=1500 mm  V1=a b c=180 150 1500=40500000 mm3 V2=(a2 h) (b2 h) (c2 h)=(1802 10) (1502 10) (15002 10)=30784000 mm3  V3=V1V2=4050000030784000=9716000 mm3  S1=V3/h=9716000/10=971600 mm2  S2=S1 dm2=S1/10000  dm2=971600/10000  dm2=97.16 dm2 S3=S2 m2=S2/100  m2=97.16/100  m2=0.9716 m2  x=n S3=12 0.9716=7287625=7287625 m2=11.6592 m2
