Question

find the area of polygons of 5cm,6cm,12cm.and 5cm,6cm,10cm.​

Answer 1

Answer:

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 1: 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.
