Answer:
rectangular container
Step-by-step explanation:
Triangular prism area: A = 1/3 * base area * height
= 1/3 * 12 * 19
= 76 cm²
Rectangular prism: A = base area * height
= 8 * 15
= 120 cm²
The rectangular container has a better value because it has a bigger area and is cheaper.
Hope this helps!
