Find the surface area of a cuboid whose length = 10 cm, breadth = 12 c

1.	Find the surface area of a cuboid whose length = 10 cm, breadth = 12 cm, height = 14 cm.
Answer» Given details are, Length of a cuboid = 10 cm Breadth of a cuboid = 12 cm Height of a cuboid = 14 cm We know that, Surface area of cuboid = 2 (lb + bh + hl) cm² = 2 (10×12 + 12×14 + 14×10) = 2 (120 + 168 + 140) = 2 (428) = 856 cm²

Find the surface area of a cuboid whose length = 10 cm, breadth = 12 cm, height = 14 cm.

Answer»

Given details are,

Length of a cuboid = 10 cm

Breadth of a cuboid = 12 cm

Height of a cuboid = 14 cm

We know that,

Surface area of cuboid = 2 (lb + bh + hl) cm²

= 2 (10×12 + 12×14 + 14×10)

= 2 (120 + 168 + 140)

= 2 (428)

= 856 cm²
