Do you mean how much paint you need to cover the prism (i.e., the surface area), or do you want a net diagram to draw/cut out?
If you mean surface area (area to paint):
- Faces: 2(8×10) + 2(5×10) + 2(5×8) = 2(80 + 50 + 40) = 340 in².
- In square feet: 340 in² ÷ 144 = 2.3611 ft² (about 2.36 ft²).
If you want paint quantity examples:
- A typical gallon covers ~350–400 ft², so you'd need only about 0.006–0.007 gallons (practically zero — well under one can).
- Even a quart (≈100 ft² coverage) would be far more than enough.
If you want a net to draw: one simple net is an 8×10 rectangle as the center, attach the other 8×10 to one long side, attach the two 5×10 rectangles to the other long sides, and attach the two 5×8 rectangles to the remaining short sides (there are several equivalent nets — tell me if you want a sketch).
