The volume of this triangular prism is 140 cubic millimeters. What is the value of d? Please need help!!

7 millimeters

Step-by-step explanation:

Volume is the area of the base times it's length.

140/10 is 14

so the area of the triangle is 14

the formula for area of a triangle is base times height divided by 2

so

d x 4/ 2 = 14

multiply both sides by 2

d x 4 = 28

divide both sides by 4

d=7

ik how do do this just give me a few minutes and i will give it to
