how to solve:
split the shape into triangles and rectangle(s) and find area of each
Answer:
By SSS Test
Step-by-step explanation:
Since the sides of both the triangle are equal
By SSS test, we can say that the both the triangles are congruent
Im assuming the base of the triangle is 4cm. The volume is

.
If the dimensions are tripled, the base is 12, the height is 24, and the length is 18. The volume is

, which is 27 times bigger.
If you are increasing each side by a factor of x, you are multiplying the original by
