First find the area of the triangle base. The area of a triangle is one-half base times height.
0.5 * 8 * 14 = 56
Now multiply the area by the length of the prism.
56 * 49 = 2744 cm^3
The answer is A
Hello!
You can use the equation to find the volume of a rectangular prism which is
V = whl
V is volume
w is width
h is height
l is length
1 1/2 = 1.5
Put in the values you know
120 = w * 8 * 1.5
Now you solve it algebraically
Divide both sides by 8
15 = w * 1.5
Divide both sides by 1.5
10 = w
The answer is 10 inches
Hope this helps!
X = -6.4
First, you would subtract 8 on both sides:
-2.5x + 8 - 8 = 24 - 8
The 8 cancels out on the left side of the equation, and 24 - 8 = 16
Next, divide both sides by -2.5, to get rid of the number that is multiplying by x.
-2.5x/-2.5 = 16/-2.5
= x = -6.4
*Remeber, when dividing a negative by a positive, the answer is negative. In this case, 6.4 is negative.
The answer is 1.7 x 10 to the power of 9
hope this helps
