Surface Area Of A Cuboid

 

The total surface area (TSA) of a cuboid is the sum of the areas of its 6 faces, which is given by:

TSA = 2 (lw + wh + hl) 

Remember the surface area is the total area of all the faces of a 3D shape.

The lateral surface area of a cuboid is given by:

LSA = 2 (lh + wh) = 2 h (l + w)

Example :

Find the total surface area of a cuboid with dimensions 8 cm by 6 cm by 5 cm.

TSA = 2 (lw + wh + hl) 

TSA = 2 (8*6 + 6*5 + 5*8)

TSA = 2 (48 + 30 + 40) 

TSA = 236 

So, the total surface area of this cuboid is 236 cm2.
