Question

2. A cuboidal box has height, length
and width as 20 cm, 15 cm and 10
cm respectively. Find its total surface
area and volume.​

Answer 1

length= 20cm

Breadth = 15 cm

Height = 10cm

TSA of cuboidal box = 2( lb+ bh+ lh )

2 ( 20× 15 + 15 × 10 + 20× 10 )

2( 300+ 150 + 200)

2× 650

1300 . Ans

Volume of cuboidal box = l× b× h

20× 15 × 10

3000 . Ans

Answer 2

Answer:

Total surface area of cuboidal box will be 1300 cm Square.

Volume of that cuboidal box will be 3000 cm cube.

Step-by-step explanation:

total surface area = 2(LB + BH + HL)

2(150+200+300)

2× 650

1300 cm square

volume of cuboid = (L×B×H)

(15×10×20)

= 3000 cm cube
