Question

What is the answer for this math problem?

Answer 1

The value of j is 9feet

Explanation:

`\hookrightarrow \sf \: v = whl`

⇒
`\sf {75.6 = (2.1)(4)(j) }`

⇒
`\sf {75.6=(2.1)(4)j}`

Step 1: Simplify both sides of the equation.

⇒
`\sf {75.6=8.4j}`

Step 2: Flip the equation.

⇒
`\sf {8.4j=75.6}`

Step 3: Divide both sides by 8.4.

⇒
`\sf { (8.4j)/(8.4) = (75.6)/(8.4)}`

⇒
`\sf {j=9}`

Answer 2

9 feet

Explanation:

v = lwh (volume equals length times width times height)

75.6 = 4 x 2.1 x d

multiply l and w, which is 4 x 2.1

75.6 = 8.4 x d

divide 75.6 by 8.4

9 = d
