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.
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.
An oven that is 4.4 cubic feet would have interior dimensions of approximately 21 inches in width, 17 inches in depth, and 19 inches in height. This size is considered medium to large and can accommodate a variety of dishes and cookware.
speed = f * lamda (wavelength) 35 * 60 2100 cm/s or 21 m/s
Considering the average density of uranium (19.05 g/cm^3), a 600 kg ball of uranium would have a volume of approximately 31,450 cm^3. This would be roughly equivalent to a sphere with a diameter of around 22 cm (8.7 inches).
77 cm × 53 cm (30 in × 21 in)
21 cm x 25 cm x 1 cm = 525 cubic centimetres.
21 in = 53.3 cm
Yes. 21 inches equates to 53.3cm: 21" x 2.54 = 53.3 cm
2/3 × 21 cm = (2 × 21)/3 cm = 14 cm
2/3 * 21 cm 42/3 cm = 14 cm -----------
About 8.3 inches.
Yes, because 11 + 15 > 21, 11 + 21 > 15, and 15 + 21 > 11
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).
