132.5 cm²

Step-by-step explanation:

The cuboid has 6 surfaces, actually 3 pairs of equal surfaces. You add the areas of each of them:

top/bottom: 2.3*7.5 =  17.25 cm²

front/back: 5*7.5 = 37.5

left/right: 2.3*5 = 11.5

add them: 17.25 + 37.5 + 11.5 = 66.25 cm²

Now double that value to get all sides: 2*66.25 = 132.5 cm²

Never forget the unit (cm²)!

You have to calculate 3 pairs of surface areas:

2 x 7.5 x 5 = 75

2 x 2.3 x 7.5 = 34.5

2 x 2.3 x 5 = 23   and that totals

132.5
