Question

to form a cuboid and find the formula for its surface area experimentally​

Answer 1

Answer:

For knowledge about cuboid refer to Activity 7.

Let the length of the cuboid be l units, breadth b units and height h units, then. Total Surface Area: Surface area (SA) or total surface area (TSA) of the cuboid. = Sum of all faces of the cuboid. = lb + lb + bh + bh + lh + lh. ⇒ SA or TSA = 2 (lb+bh+hl) sq.units.

Answer 2

Answer:

hope it's help

Step-by-step explanation:

Theory

For knowledge about cuboid refer to Activity 7.

Let the length of the cuboid be l units, breadth b units and height h units, then

Total Surface Area: Surface area (SA) or total surface area (TSA) of the cuboid

= Sum of all faces of the cuboid

= lb + lb + bh + bh + lh + lh

⇒ SA or TSA = 2 (lb+bh+hl) sq.units

i.e. SA or TSA =2 (Length x Breadth + Breadth x Height + Height x Length)

Lateral Surface: Area If out of the six faces of a cuboid, we leave the bottom and top faces and find the area
