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;
![n = (d)/(t)](https://img.qammunity.org/2022/formulas/mathematics/high-school/5eglzexbuyuhyeo4hd5qhfihmex4z03q2d.png)
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;
![n = (10 \, mm)/(0.5 \, mm) = 20](https://img.qammunity.org/2022/formulas/mathematics/high-school/mfsoo5hr61ltoqlpac0rg614u1pfsoatx4.png)
The number of triangles it would take to fill up the prism, n = 20
