21 centimeters is 8.27 inches.
It is a cube with sides of 50 cm.
speed = f * lamda (wavelength) 35 * 60 2100 cm/s or 21 m/s
Density= Mass/Volume However a cm is a length NOT a volume (volume is cubic cm) so your question as asked can not be answered. However if you meant 21 cubic centimeters, then the density would be 2.71 grams per cc.
For an uranium metal density of 19.05 g/cm3 the sphere radius 1s 19,59 cm.
Without specific measurements for the small cube there's no way to tell; it could be anywhere from 1 small cube to an infinite number. Assuming, however, that the small cube is 1 cm x 1 cm x 1cm (1 cm cubed), then 8000 of the small cubes would fit inside. That's 20*20*20, because the big cube is 20 times as large in three different dimensions.
77 cm × 53 cm (30 in × 21 in)
21 cm x 25 cm x 1 cm = 525 cubic centimetres.
21 in = 53.3 cm
2/3 × 21 cm = (2 × 21)/3 cm = 14 cm
2/3 * 21 cm 42/3 cm = 14 cm -----------
Yes, because 11 + 15 > 21, 11 + 21 > 15, and 15 + 21 > 11
Yes. 21 inches equates to 53.3cm: 21" x 2.54 = 53.3 cm
ICD 10 CM contains 21 Chapters.
A circle with a radius of 21 cm has an area of ~1,385.44 square cm
They are 8 to 9 in (21 to 23 cm) long and weigh 1.5 to 1.8 oz (42 to 51 g).
