Answer:
2. 20
Explanation:
2. The distance from one base of the prism to the other base of the prism, d = 10 mm
The thickness of each triangle to be used to fill the prism, t = 0.5 mm
The number of triangles needed, n, is therefore;
Where;
d represents the distance between the bases of the prism, t, represents the thickness of each triangle, and n represents the number of triangles it would take to fill up the prism
Therefore;
The number of triangles it would take to fill up the prism, n = 20
