Question

if a cuboid with height 6cm , length 11cm, breath 9cm find its total surface area and volume​

Answer 1

$\large\bf\underline{Given:-}$

• Length ( L ) = 11 cm
• Height ( H ) = 6 cm
• Breadth ( B ) = 9 cm

$\large\bf\underline{Given:-}$

• Total surface area of cuboid
• Volume of cuboid

$\large\bf\underline{Formulae :-}$

★ Total surface area = 2 ( LB + LH + HB )

★ Volume of cuboid = L × B × H

$\large\bf\underline{Solution:-}$

★ Firstly we will find Total surface area or Cuboid

★ Put the values given in the formula mentioned above .

• Total surface area
• = 2 (11×9 + 11×6 + 9×6 )
• = 2 (99 + 66 + 54)
• = 2 (219)
• = 438 Cm²

★ Now , We will find the volume of the cuboid

★ Put the values in the formula mentioned above

• Volume =
• = 6 × 9 × 11
• = 594 cm³
