Answer:
The total surface area of the cuboid is 280.
Length: 5 cm
Width: 6 cm
Height: 10 cm
Total Surface Area of Cuboid = 2*((Length of Cuboid*Height of Cuboid)+(Height of Cuboid*Width of Cuboid)+(Length of Cuboid*Width of Cuboid))
SATotal = 2*((l*h)+(h*w)+(l*w)) --> 2*((5*6)+(6*10)+(5*10))
SATotal = 280
