All the sides of a CUBE are equal..
Therefore, we can conclude that the formula for the volume of a cube is:
=side³=s³
Or =Base area×height
Which is the same thing, because we multiply the same numbers thrice.
V of cube=side³
=7³ (side length is 7 in)
=343 in³
A) .05n + .10d + .25 q = 10.30
B) d +2 = q
C) n = 3q
Substituting equations B and C into A
A) .05*3q + .10(q-2) + .25 q = 10.30
A) .15q + .1q -.2 + .25q = 10.30
A) .50q = 10.50
21 quarters
C) n = 3q
C) n = 3*21
63 nickels
B) d +2 = q
d + 2 = 21
