Question

Find the volume and the total surface area of a cuboid whose dimension are 2m, 80cm, 60cm

Answer 1

Answer :-

• Volume = 960000cm³

• Total surface area = 65600cm²

_____________________

Given :-

• Dimensions of a cuboid as 2m, 80cm and 60cm.

To Find :-

• Volume and total surface area of the cuboid.

____________________

Solution :-

• Length = 2m = 200cm

• Breadth = 80cm

• Height = 60cm

★We know that the formula of volume of the cuboid is

length × breadth × height

=> 200 × 80 × 60

=> 960000 cm³

____________________

★ We know that the formula of total surface area of the cuboid is

2 (lb + bh + lh)

=> 2(200×80 + 80×60 + 60×200)

=> 2(16000 + 4800 + 12000)

=> 2(32800)

=> 65600 cm²

Hence, the volume and total surface area of the cuboid are 960000cm³ and 65600cm² respectively.

Answer 2

Answer :

${\red\bigstar\Large\bold{\underline{\textsf{\green{Given:}}}}}$

• Length = 2 m = 2 × 100 = 200 cm

• Breadth = 80 cm

• Height = 60 cm

${\red\bigstar\Large\bold{\underline{\textsf{\green{To\:Find:}}}}}$

• Volume and Total Surface Area of Cuboid

${\red\bigstar\Large\bold{\underline{\textsf{\green{Sølution:}}}}}$

☯ FORMULA USED :

$\bold{\boxed{\sf{\red{Volume\:of\:cuboid\:=\:Length \times Breadth \times Height}}}}$

➡ Volume = 200 × 80 × 60

Volume = 9, 60, 000 cm³

☯ FORMULA USED :

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

➡ TSA = 2(200 × 80 + 80 × 60 + 60 × 200)

➡ TSA = 2(16000 + 4800 + 12000)

➡ TSA = 2(32, 800)

➡ TSA = 65, 600 cm²
