The volume of the rectangular prism is 240 cubic centimeters. A rectangular pyramid has the same length, width,and height as a p
LuckyWell [14K]
The volume of the pyramid would be 80 cubic centimeters. The reason for this is because the formula for volume of a pyramid is 1/3bh, so if all the dimensions are the same for both figures, just divide the volume of the prism by three to find the volume of the pyramid. If you do this 240÷3=80 or the volume of the pyramid.

Solve for m.<br> m/9 + 2/3 =7/3
Nuetrik [128]

Answer:

m= 15

Step-by-step explanation:

\frac{m}{9}  +  \frac{2}{3}  =  \frac{7}{3}

To solve for m, start by moving the constants (numbers that are not attached to any variable) to the other side of the equation.

\frac{m}{9}  =  \frac{7}{3}  -  \frac{2}{3}

Simplify:

\frac{m}{9}  =  \frac{5}{3}

Multiply both sides by 9:

m =  \frac{5}{3}   \times 9

Crossing out 3 from the denominator and from 9:

m= 5(3)

m= 15
