Answer:
A = 62 squares
Step-by-step explanation:
(a) Drawing the net
Draw your net in the following sequence.
- Draw a 3×5 bottom.
- Add a 2×5 side on each side of the bottom.
- Add the 2×3 front and back to the top and bottom of the bottom.
- Finally, add the 3×5 top on one of the sides.
Your orthogonal drawing should look like the Figure below.
(b) Surface area
The formula for the surface area of a rectangular prism is
A = 2(lw +lh + wh)
l = 5; w = 3; h = 2
A = 2(5×3 + 5×2 + 3×2)
A = 2(15 + 10 + 6)
A = 2 × 31
A = 62
The surface area of the prism is 62 squares.
