4=z/3
solve for z
z=8
z=12
z=2
z=7​

z=12

Step-by-step explanation:

eliminate fraction denominators

4=3

4=\frac{z}{3}4=3z

3⋅4=3⋅3

3 \cdot 4=3 \cdot \frac{z}{3}3⋅4=3⋅3z

2

Cancel multiplied terms that are in the denominator

3⋅4=3⋅3

3 \cdot 4=3 \cdot \frac{z}{3}3⋅4=3⋅3z

3⋅4=

3 \cdot 4=z3⋅4=z

3

Multiply the numbers

3⋅4=

12=

396

Step-by-step explanation:

the volume of a rectangular is calculated as V=l×w×h

l=11, w=12, h=3

V=11×12×3

V= 396
