Answer:
C. x = 3cm
Step-by-step explanation:
The formula for volume of a triangular prism is
<u>V = base * height</u>
x in this case equals height, and the base is the area of the triangular base, which is
<u>A(triangle) = 1/2 b*h</u>
= 1/2 7*10 = 35 square centimeters
Plug this back into our formula:
V = base * height
105 = 35x
Solve for x.
105/35 = x
<u>C. x = 3 cm</u>
