Answer 1
Given
- Area of square:- 64cm²
To Find
- Side of the square

⇛ Side of square = 18cm²
So, the side of the square is 18cm².
Answer 2
Given
- Side of cube:- 7cm
To Find
- Volume of cube
Concept Knowledge
As we have given the side, and formula for finding volume of cube is side³, we will put values and find the answer.
According to Question
⇛ Volume of cube = side³
⇛ Volume of cube = 7³
⇛ Volume of cube = 343cm³
So, the volume of cube is 343cm³.
Answer 3
Given
- Lenght of gift box:- 20cm
- Breadth of gift box:- 15cm
- Height if gift box:- 6cm
To Find
- Volume of gift box (cuboid)
Concept Knowledge
As we know the formula of finding volume is lenght × width × height, we will put values and find the answer.
According to Question
⇛ Volume of cuboid = lenght × breadth × height
⇛ Volume of cuboid = 20×15×6
⇛ Volume of cuboid = 1,800cm³
So, the volume of gift box is 1800cm³.
