The objective lens (right above the slide stage) is 4x. The eyepiece (what you look into) is 10x. 4 times 10 = 40. Whatever the objective lens power is, you have to multiply it by the eyepiece power (usually 10x) to get the overall magnification.
40 quarts is the same as 10 gallons.
By unit of length and distance and conversion ,we can say that1 cm=10 mm40 cm=400 mm
Exactly 40+10+40+10 = 100cm which is its perimeter
