Question

find the total surface area of a cubiod whose dimension are 18 m, 12 cm And 15 cm​

Answer 1

${\boxed{\boxed{\red{\mathcal{CORRECT\: QUESTION:}}}}}$

• Find the total surface area of a cubiod whose dimension are 18 cm, 12 cm and 15 cm.

${\boxed{\boxed{\red{\mathcal{ANSWER:}}}}}$

• TSA of cuboid = 1332 cm².

Given:

• Length of cuboid (L) = 18 cm
• Breadth of cuboid (B) = 12 cm
• Height of cuboid (H) = 15 cm

To Find:

• TSA of cuboid.

${\boxed{\boxed{\red{\mathcal{SOLUTION:}}}}}$

$\implies$ TSA of cuboid = 2[LB + BH + HL]

$\implies$ TSA of cuboid = 2[18 × 12 + 12 × 15 + 15 × 18]

$\implies$ TSA of cuboid = 2[216 + 180 + 270]

$\implies$ TSA of cuboid = 2[666]

$\implies$ TSA of cuboid = 1332 cm²

Hence, Total surface area of cuboid = 1332 cm².

Answer 2

QUESTION

find the total surface area of a cubiod whose dimension are 18 m, 12 cm And 15 cm

Answer:

• TSA of cuboid = 1332 cm².

Given:

• Length of cuboid (L) = 18 cm
• Breadth of cuboid (B) = 12 cm
• Heightof cuboid (H) = 15 cm

To Find:

TSA of cuboid.

SOLUTION:

⟹ TSA of cuboid = 2[LB + BH + HL]

⟹ TSA of cuboid = 2[18 × 12 + 12 × 15 + 15 × 18]

⟹ TSA of cuboid = 2[216 + 180 + 270]

⟹ TSA of cuboid = 2[666]

⟹ TSA of cuboid = 1332 cm²

Hence, Total surface area of cuboid = 1332 cm².
