find surface area!!
​

Answer 1

Step-by-step explanation:

The figure consists of 6 rectangle and 2 triangle faces.

Surface area (excluding bottom side) is:

• S = 2(2.4*1.6 + 1.3*1.6 + 1.5*1.6 + (1/2)*2.4*0.9) = 18.8 yd²

Total surface area (including bottom side):

• A = 18.8 + 2.4*1.3 = 21.92 yd²

Answer 2

Answer:

$s \: = \: 2(2.4 \times 1.6 + 1.3 \times 16 + 1.5 \\ \times 16 + ( \frac{1}{2} ) \times 2.4 \times 0.9) \\ \\ = 18.8y {d}^{2} \\ \\ total \: surface \: area \: ( \: including \\ \\ bottom \: side \: ) \\ \\ a \: = 18.8 + 2.4 \times 13 \\ \\ = 21.92y {d}^{2}$
