Question

The base is a square, 4.5 on a side. The height is 5cm

Looking for the volume, help!

Answer 1

Given :-

• Length and Breadth = 4.5 cm
• Height = 5cm

To Find :-

• Volume of the shape

Solution :-

Volume = l ×b ×h /3

• putting the known values ,

Volume = 4.5 × 4.5 × 5 cm/3³

Volume = 101.25/3 cm³

Volume = 33.75 cm³

Answer 2

• Volume = 33.75 cm³

Explanation:

After reading question we can understand that the all these measurements are of pyramids .

So In the question we are given ,

• Base of square = 4.5 cm

• Height of pyramid = 5 cm

We know that in pyramid length and width are equal to base of a square . Therefore ,

• Length of pyramid = 4.5 cm

• Width of pyramid = 4.5 cm

Formula :

`\rightarrow \blue{\boxed{ \sf{Volume \: of \: pyramid = (lwh)/(3) }}}`

Where ,

• l refers to length of pyramid

• w refers to width of pyramid

• h refers to height of pyramid

Now , substituting values of l , w and h :

`\longmapsto \: (4.5 * 4.5 * 5)/(3)`

Now , by multiplying 4.5 , 4.5 and 5 , We get :

`\longmapsto \: (101.25)/(3)`

Now , by dividing 101.25 by 3 , We get :

`\longmapsto \: \red{\boxed{33.75}}`

• Therefore , volume of pyramid is 33.75 cm³ .
