Answer:
Step-by-step explanation:
To solve a formula for one of its variables do that
- Underline the variable
- Separate it on one side and the other terms on the other side
- Make its coefficient equals 1
Let us use these steps to solve our question
∵ V = b²h
→ Underline b
∴ V = <u>b²</u>h
→ Multiply both sides by 3 to cancel the denominator on the right side
∴ 3V = <u>b²</u>h
→ Divide both sides by h to move it to the other side
∴
→ To find b take √ for both sides
∴
→ The square root will cancel the power 2 of b
∴
→ Switch the two sides
∴
