1 answer:

6 0

Each of the triangles are equal in base length, height, and area. Remember the formula for the area of a triangle. The area of any triangle is 1/2 times the length of the base (which, in the polygon, is the length of a side) multiplied by the height (which is the same as the apothem in regular polygon).

lana [24]

Im assuming the base of the triangle is 4cm. The volume is $96cm^{3}$ .
If the dimensions are tripled, the base is 12, the height is 24, and the length is 18. The volume is $2592cm^{3}$ , which is 27 times bigger.
If you are increasing each side by a factor of x, you are multiplying the original by $x^{3}$
