Answer:
120 cm cubed
Step-by-step explanation:
first we need to find the size of the triangular face. we can do this by taking the height and with of the base, multiplying them, then dividing by two (3*8)/2
which gives us 12, so now we multiply by 10 to get the volume of the full prism. 12*10=120
For the top shape, x = 11, y = 10 and z = 14.
Start with the equation: 11y + 7y = 180 because those two angles are supplementary. Solving that will give you that y = 10.
The angle that is labelled 7y is therefore 70 degrees. We can write the following equation will the 5x because it is corresponding to the 70 degree angle.
5z = 70
z = 14
And we can also write and solve for the x, using the 70 degree angle.
70 + 10x = 180
10x = 110
x = 11
$65.80
$26.32/8=$3.29 for a gallon
$3.29 x 20 = $65.80.
Hope this helps
