Question

Q. Find the total surface area of the cuboid of length 15cm, breadth 10cm and height 5cm.​

Answer 1

Answer:

550cm^2 is your answer

Step-by-step explanation:

TSA of cuboid = 2 (lb+by+hl)

= 2( 15×10+10×5+5×15 )

= 2( 150 + 50 + 75 )

= 2(275)

= 550cm ^2

Answer 2

Given :

• Length of cuboid (L) = 15cm
• Breadth of cuboid (B) = 10cm
• Height of cuboid (H) = 5cm

$\:$

To find :

• TSA of cuboid.

$\:$

Solution :

• In the question Length, Breadth and height are given and we have to find the Total surface area (TSA) of cuboid. So,By using the formula of 2 (lb + bh + hl) we can find the Total surface area of cuboid.

$\:$

${\underline{\boxed {\red {\sf {TSA \: of \: cuboid = 2 (lb + bh + hl)}}}}}$

$\:$

➤ 2 (15 × 10) + (10 × 5) + (15 × 5)

➤ 2 (150 + 50 + 75)

➤ 2 × 275

➤ 550cm²

$\:$

$\therefore\:$ TSA of cuboid is 550cm²
