Question

Pick any cuboidal box available at home (example- shoe box) and measure it's length, breadth and height using any scale. Calculate is total surface area, lateral surface area and volume.

Class 8 CBSE​

Answer 1

Answer:

shoe box

l= 30 cm

b= 15cm

height = 10cm

total surface area = 2 x ( 30 x 15 ) + ( 30 x 10  ) + ( 15 x 10  )

= 2 x 450 + 300 + 150

900 x 2

1800 cm²

lateral surface

2 x 30 +15  x10

750 cm²

volume

30 x 15 x 10

4500 cm²

Step-by-step explanation:

Lateral surface area of a cuboid = 2(l+b)h

Total surface area of a cuboid = 2 [( lb ) + ( lh ) + ( bh )]

Volume of cuboid (v) = l × b × h
