Question

What is the surface area of the prism

Answer 1

204 mm would be the answer.

Reasoning of this is because 15mm x 3mm= 45mm > 45mm x 4mm= 180mm

4mm x 3mm= 12mm > 12mm x 2mm= 24mm

(Multiply 12 x 2 because there are 2 squares on both sides)

Then you add 180mm + 24mm= 204mm

Answer 2

204 mm.

Explanation:

To find the surface area, add together the area of each side. To find the area of the rectangular sides, multiply 15 mm by 3.

15*3= 45

Since there are 4 rectangular sides, multiply your answer by 4.

45*4=180

Next, to find the square sides, multiply 4 mm by 3.

4*3=12

Since there are 2 square sides, multiply your answer by 2.

12*2=24

Finally, add your answers together to find the total surface area.

180+24=204
