Question

The length of one side of a cube is
5.5cm. The volume of the cube,
according to idea of significant
figures is:​

Answer 1

side of cube =5.5cm

area of cube =a^3. (where a is the side of cube)

so, ar. =(5.5)^3=166.375

Answer 2

Given:

The length of one side of a cube is  5.5 cm

To find :

The volume of the cube.

Formula to be used:

Volume of the cube = a³

Solution:

Step 1 of 2

Let the side of the cube is 5.5 cm

Therefore, a = 5.5 cm

To find the volume of the cube,

Substitute 'a, in the following formula,

Volume of the cube = a³

Volume of the cube = (5.5)³

Volume of the cube = 166.375 cm³

Step 2 of 2

According to idea of significant  figures,

Volume of the cube = 1.66375 × 10² cm³

Since 3 is less than 5, We can write it as,

Volume of the cube = 1.66 × 10² cm³

Final answer:

The length of one side of a cube is  5.5cm. Then, the volume of the cube is 1.66 × 10² cm³.
