Answer 1

Answer: I am pretty sure it is 31 square units

Step-by-step explanation: when it says area you count all the blocks inside

Answer 2

A = 62 squares

Explanation:

(a) Drawing the net

Draw your net in the following sequence.

1. Draw a 3×5 bottom.
2. Add a 2×5 side on each side of the bottom.
3. Add the 2×3 front and back to the top and bottom of the bottom.
4. 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.
