Answer:

The missing length is 12 meters.

Step-by-step explanation:

9+9+x+x=42

<em>Subtract 9 from both sides</em>

9+x+x=33

<em>Subtract 9 from both sides</em>

x+x=24

2x=24

<em>Divide both sides by 2</em>

x=12

The missing length is 12 meters.

A rectangular prism has a length of 8 in., a width of 4 in., and a height of 2 1/4 in.
marishachu [46]

The number of cubes needed to fill the rectangular prism 4608 cubes.

<h3>How to find volume of rectangular prism and cube?</h3>

volume of rectangular prism = lwh

where

  • l =length
  • w = width
  • h = height

Therefore,

volume of the rectangular prism = 8 × 4 × 9 / 4 = 72 inches³

volume of the cube = l³

where

  • l = length

Therefore,

volume = (1 / 4)³

volume of the cube = 1  / 64 inches³

Therefore,

The number of cubes needed to fill the rectangular prism = 72 ÷ 1 / 64

The number of cubes needed to fill the rectangular prism = 72 × 64 = 4608
