Answer: 11 1/2 laps
Step-by-step explanation:
18-7=11
1/4-3/4=1/2
We will solve this using volume of cube formula. Since, It is a cube all the sides are equal in length. Let's find the length with volume... ~

Where A is the side of cube
We have, Volume = 64
Let's solve for a

Swap the sides of the equation

Take the cube root of 64
![\sf \to \: a = \sqrt[3]{64}](https://tex.z-dn.net/?f=%20%5Csf%20%5Cto%20%5C%3A%20a%20%3D%20%20%5Csqrt%5B3%5D%7B64%7D%20)
Solve for root

<em>Thus, Each side of the cube measures 4 unit..!</em>

Answer:
A. 2.1
Step-by-step explanation:
Put the numbers in the equation and do the arithmetic.
1/R = 1/(3 1/2) +1/(5 1/4)
1/R = 1/(7/2) +1/(21/4) = 2/7 +4/21 = (6 +4)/21
R = 1/(10/21) = 21/10
R = 2.1
