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)
• Dimensions of cuboid
Length (1)= 15cm
• Breadth (b) 7cm
Height (h)= 9cm
To Find :
• We have to find the surface area of the cuboid
Solution
As we know that
Total Surface area of cuboid
=2(Lb + bh + hO)
Now put the given values in the formula :
→→→ Surface Area = 2{(15 x 7) + (7 × 9) + (9
→→→ Surface Area = 2(105 +63 +135)
--> Surface Area = 2 x 303
-- Surface Area 606cm²

* Volume of cuboid = l × b ×x h
*L.S.A of cuboid = 2(l+ b) x h
* Diagonal of cuboid √ l² + b² + h²
