Answer:

80 cuboids

Explanation:

To find out the answer we must find the surface area of the cuboids;

2lw+2lh+2wh;

2*20*3+2*20*10+2*3*10;

580

46400/580 is the number of cuboids she can paint;

80

The total surface area of the cuboid can be calculated by adding the area of all six sides.

2(lw + lh + wh)

2(20x3 + 20x10 + 3x10)

2(60 + 200 + 30)

2(290)

580

Therefore, the surface area of one cuboid is 580 cm².

To find how many cuboids Finnley can completely cover with 46,400 cm² of paint, we need to divide the total surface area of the cuboid by the surface area of one cuboid.

46,400 / 580 = 80

Therefore, Finnley could completely cover 80 cuboids like the one shown with the tin of orange paint.
