Unfortunately, 0.5 m cube is an ambiguous term It can mean a cube measuring 0.5m along each edge, or one whose total volume is 0.5 m3 (edges of 0.794 m approx).
In the first case, 0.5m * 0.5m * 0.5m = 0.125 m3 = 0.125*109 mm3
or 1.25*108 mm3 or 125 million mm3.
In the second case, you have 0.5m3 which equals 500 million mm3.
The surface area of cube M is 6(10 mm)2 = 6(100 mm2) = 600 mm2 The surface area of cube N would be 6(20 mm)2 = 6(400 mm2) = 2,400 mm2
1 m = 1,000 mm (1m x 1m x 1m) = 1 m3 = (1,000mm x 1,000mm x 1,000mm) = 1,000,000,000 mm3
1 m = 1,000 mm 800 m = 800,000 mm
10 m = 10000 mm
0.000004 m = 0.004 mm
The surface area of cube M is 6(10 mm)2 = 6(100 mm2) = 600 mm2 The surface area of cube N would be 6(20 mm)2 = 6(400 mm2) = 2,400 mm2
1 m = 1,000 mm (1m x 1m x 1m) = 1 m3 = (1,000mm x 1,000mm x 1,000mm) = 1,000,000,000 mm3
1 m = 1,000 mm 2 m = 2,000 mm 3 m = 3,000 mm 4 m = 4,000 mm 5 m = 5,000 mm 6 m = 6,000 mm
1 m = 1000 mm
1 m = 1,000 mm 8 m = 8,000 mm
1 m = 1,000 mm 800 m = 800,000 mm
10 m = 10000 mm
There are 1,000 mm in a meter (m), so there is 1.548 m in 1548 mm.
Assuming m = metres and mm = millimetres, 64789 mm = 64.789 m
1 m = 1,000 mm 1 m³ = 1 m × 1 m × 1 m = 1,000 mm × 1,000 mm × 1,000 mm = 1,000,000,000 mm³
42.7 m = 42700 mm.
2 m = 2000 mm.
