Answer:
12 cubic inches
Step-by-step explanation:
The formula for the area of a triangle is : [tex]\frac{base*height}{2}[/tex]
To work out the volume you would first need to work out the area of a triangle. you can do this by first multiplying base of 4 by the height of 3, this gives you 12.
The next step is to divide 12 by 2, this gives you 6. this is because the formula is the same for a square, however a triangle is half of a square with the same dimensions.
Now that you have worked out the area, to work out the volume you would
multiply the area of 6 by the width of 2, this gives you 12 cubic inches.
1) Multiply 4 by 3.
[tex]4*3=12[/tex]
2) Divide 12 by 2.
[tex]12/2=6[/tex]
3) Multiply 6 by 2.
[tex]6*2=12inches^3[/tex]
