Answer 1

Answer:

a) 84000 cm³

b) 84 L

Explanation:

GIVEN :-

• Width of aquarium = 35 cm
• Length of aquarium = 60 cm
• Height of aquarium = 40 cm

TO FIND :-

• Volume of aquarium (in cm)
• Volume/Capacity of aquarium (in L)

FACTS TO KNOW BEFORE SOLVING :-

• 1 cm³ = 1 mL
• 1 L = 1000 mL or 1 mL = $\frac{1}{1000}$ L
• Volume of a cuboid = Length × Width × Height

PROCEDURE :-

Volume of the aquarium = 60 × 35 × 40 = 84000 cm³

In order to find the capacity of aquarium (in L) , first we need to change the volume in cm³ to mL .

⇒ Volume of aquarium = 84000 cm³ = 84000 mL  (∵ 1 cm³ = 1 mL)

∴ Volume of aquarium (in L) = $\frac{84000}{1000} = 84L$ (∵ $1mL = \frac{1}{1000} L$)
