Answer:

x=3

Step-by-step explanation:

let x represent the space provided

(4+7)×3=(4×3)+(7×x)

11×3=12+7x

33=12+7x

Group like terms

33-12=7x

21=7x

Divide both side by the co-efficient of x

21/7=7x/7

3=x

Therefore x=3

Which will have a greater effect on the volume of the prism: doubling the height or doubling the width? Explain your reasons.

statuscvo [17]

Doubling the width has a greater effect on volume.
The volume of a prism is calculated by this formula:
Prism Volume = Area of Base • Height
The Area of the Base is calculated by this formula:
area = n * side² / (4*tan(180 / # of sides)

So, we see that doubling the width (the side length) will increase the volume by 4 whereas doubling the height only doubles the volume.
