Atriangular prism is 14.3 millimeters long. it has a triangular face with a height of 12 millimeters. the volume of the prism is 1,123.98 cubic millimeters. what is the base of its triangular face?

Answer

13.1 millimeters

Explanation

The volume of any regular object is found by;

Volume = base area × length.

In the question, the base is a triangle of height  12 millimeters and a base length L.

The length of the prism is  14.3 millimeters.

∴ Volume = base area × length.

   1,123.98 = (1/2 × 12 × L) × 14.3

   1,123.98 = 85.8 L

   L =  1,123.98/85.8

       = 13.1 millimeters

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
