Answer: 90 inches
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a rectangular prism =area of the base x length
Area of the base is the area of a triangle:
Area of a triangle = base x height x 1/2
Replacing with the values given:
A = 4 x 3 x 1/2 = 6 in2
Back on the volume formula:
V = A x h = 6 x 15 = 90 cubic inches
Feel free to ask for more if needed or if you did not understand something.
That’s a hell of a question but I think you need to multiply 480, 6 times

Step-by-step explanation:
<u>Step 1: Define equation</u>
5x + 2 = 20
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 2 on both sides: 5x = 18
- Divide 5 on both sides: x = 18/5
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 5(18/5) + 2 = 20
- Multiply: 18 + 2 = 20
- Add: 20 = 20
Here we see that 20 does indeed equal 20.
∴ x = 18/5 is a solution to the equation.
