Answer:
CU = 12
Step-by-step explanation:
Clearly from the diagram of the triangle we can say that,
AD, BE and CF are the medians of the triangle ABC , since they are bisecting the sides of the triangle equally.
Also , U is the intersection point of the these mediands of the triangle whic is known as centroid of the triangle.
Now, from the property of the centroid , centroid divides the median in the ratio of 2 :1 from the point C .
Thus CU will be times of CF (median) .
Given is Cf equals 18 ,
Thus , CU = ×18 = 12.
So, CU equals 12 .

The surface area of the triangular prism is 1664 square inches.
Explanation:
Given that the triangular prism has a length of 20 inches and has a triangular face with a base of 24 inches and a height of 16 inches.
The other two sides of the triangle are 20 inches each.
We need to determine the surface area of the triangular prism.
The surface area of the triangular prism can be determined using the formula,
where b is the base, h is the height, p is the perimeter and l is the length
From the given the measurements of b, h, p and l are given by
,
,
and
Hence, substituting these values in the above formula, we get,
Simplifying the terms, we get,
Adding the terms, we have,
Thus, the surface area of the triangular prism is 1664 square inches.
