The 10x means it magnifies ten times
The 70mm means the final lenses (that point to the image) are 70mm in diameter.
The larger the diameter, the more light that can enter the binoculars and so the easier it is to see the image. So binoculars 10x50mm and 10x70mm both magnify ten times, but the 70mm diameter lenses allow more light in and so should give a better image.
So the larger the second number, the better the image [should be] for a given magnification; however, the larger the second number the larger (and heavier) binoculars become.
Bushnell manufactures various models and sizes of binoculars, all for different prices. For example, the Legend Ultra HD 10 by 36 mm. binoculars are roughly $370 USD. The 8 by 42 mm. binoculars of the same model are roughly $390 USD.
1 cm = 10 mm 7 cm = 70 mm
multiply by 10= 700 mm
370 mm 1 cm = 10 mm 1 mm = 0.1 cm
There are 10mm in a centimetre. You to multiply by 10 to convert cm to mm. 70*10 is 700mm.
There are 10 millimetres in a centimetre. You need to multiply cm by 10. Therefore 7*10 is 70 millimetres.

10 mm = 1 cm 20 mm = 2 cm 30 mm = 3 cm . . 70 mm = 7 cm
1 cm = 10 mm 7 cm = 70 mm
One cm contains 10 mm. So, 7 x 10 = 70 mm.
multiply by 10= 700 mm
370 mm 1 cm = 10 mm 1 mm = 0.1 cm
70 mm 1 cm = 10 mm 1 mm = 0.1 cm
1 cm is equal to 10 mm so 70 cm would be 700 mm.
70mm and 7cm equal. There are 10 mm in one cm. So if you have 7cm just multiply by ten and you will get 70!:)
Presumably you mean "radius"... 70 pi sq mm
70 millimeters. 1 cm = 10 mm 1 mm = 0.1 cm
