Q. What is the surface area of this cuboid with dimensions 6cm,8cm and 3cm ?
Calculate Area of Faces: Calculate the area of each face of the cuboid.- Area of face 1 (6cm×8cm): 6×8=48cm2- Area of face 2 (6cm×3cm): 6×3=18cm2- Area of face 3 (8cm×3cm): 8×3=24cm2
Double Area of Faces: Each face has an opposite face of the same area, so double the area of each face.- Total area for pairs of faces: (48×2)+(18×2)+(24×2)=96+36+48
Find Total Surface Area: Add the areas of all face pairs to find the total surface area.- Total surface area =96+36+48=180cm2
