Answer 2

total surface area

Answer 3

I think it is 304

Answer 4

Answer 5

right @jiteshmeghwal9

Answer 6

ok @janett77

Answer 7

right

Answer 8

The top, bottom, and lateral sides are easiest to calculate right off the bat:
\[Top = 6 \times 7 = 42\]
\[Bottom = 7 \times 12 = 84\]
\[Side = 5 \times 7 = 35\]
\[Trapzoid = \frac{1}{2} \times 4 \times (6 + 12) = 2 \times 18 = 36\]
Summing:
\[Top + Bottom + 2 \times Side + 2 \times Trapezoid = 42 + 84 + 70 + 72 = 268\]
