Find the total surface area of this cuboid.
15 cm
2 cm
4 cm

SA=2lw+2lh+2hw, to find the surface area and answer is 66

Step-by-step explanation:

need a thans please amke me brainiest

76cm²

Step-by-step explanation:

There are 6 sides in a cuboid and there are 3 different types of sides with different dimensions and 2 of each unique side.

Total surface area of cuboid = (2 × 4 × 2) + (2 × 4 × 5) + (2 × 5 × 2)

                                                = 16 + 40 + 20

                                                = 76cm²

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
