150 x 150 = 22, 500 sq mm; 1000 x 1000 = 1,000,000 sq mm; 1,000,000 / 22,500 = 44.44 blocks
10mm=1cm 1cm/10mm=x/150mm cross multiply 150mmx1cm=150cm(mm) divide by 10mm 150cm (mm)/10mm= 15cm

It is 120 mm^2.

Assumed that 150mm is the diameter of the PVC pipe, then radius is 75mm and the length is 1 meter or 1000mm. The volume of the cylinder is pi x r x r x h and in this case it would be 3.1415 x 75 x 75 x 1000 = 17670937.5 cubic mm which is 17670.9375 cubic cm which is 17.6709375 liters
150 x 150 mm is a 2-dimensional figure. A cube is a 3-dimensional object and so you cannot have a 150x150 mm cube. Furthermore, cubes with sides of 150 mm are rarely used. I have not used one ever - and I am over 60!
If 150 / x = 66, then x = 2.2727 cmSuppose the length is L cm.Then 150*L cm = 66 cmSo L cm = 66 cm/150 = 66/150 cm = 0.44 cm = 4.4 mm.
It is equivalent to 2578.56 square millimeters
