3[4(23)-52+7(8+42)-16]

3 x (4 x 8 - 52 + 7 x (8 + 42) - 16)

3 x (32 - 52 + 7 x (8 + 42) - 16)

3 x (16 – 52 + 7 x (8 + 42))

3 x (16 - 25 + 7 x (8 + 42))

3 x (-9 + 7 x (8 + 42))

3 x (-9 +7 x (8 + 16))

3 x (-9 + 7 x 24)

3 x (-9 + 168)

3 x 159

477

What is the surface area of the solid shown below?

Ugo [173]

Answer:

$\text{C. }156\:\mathrm{cm^3}$

Step-by-step explanation:

The surface area of the triangular prism consists of three rectangles and two triangles.

Rectangle One - 5 x 12 = 60 cm^2

Rectangle Two - 4 x 12 = 48 cm^2

Rectangle Three - 3 x 12 = 36 cm^2

Triangles - 2 x 1/2 x 3 x 4 = 12 cm^2

Thus, the total surface area of the solid is $60+48+36+12=\boxed{\text{C. }156\:\mathrm{cm^3}}$
