Marks's dad drove 123 miles in 2 hours. At that rate, how many miles would he drive in 5 hours?

He drove 123 miles in 2 hours. If you go 100 miles in 2 hours that means you went 50 miles in one hour right? Using the same logic we can convert 123 miles in 2 hours to 61.5 miles per hour and then multiply it by 5.

A rectangular prism is packed with cubes that measure 1/4 inch on each side. What is the volume, in cubic inches, of the rectang

Vladimir79 [104]

V = n X V(cube)

<u>Explanation:</u>

Given:

Side of the cube,a = $\frac{1}{4}$

Volume of the cube = a³

So, the volume of the cube, V is

V(cube) = $(\frac{1}{4})^3$

V(cube) = $\frac{1}{64}$

Let the number of cubes be n

Let V be the volume of the rectangular prism

Volume of rectangular prism = number of cubes X volume of cubes

V = n X V(cube)

If the number of cubes are known then substitute the value in the above given formula.
