A rectangular room 8cm long by 5cm wide contains 120cm3 of air.calculate the hieght of the room

well, you know that

8*5*h = 120
so now just solve for h

what is this -- a doll house, with dimensions in cm?

How many litres of water does a 5cm,4cm,3cm tank hold.

To calculate the height of the room, you can use the formula for calculating the volume of a rectangular prism:

Volume = Length x Width x Height

In this case, the volume of the room is given as 120cm³, the length is 8cm, and the width is 5cm.

So, we have:

120cm³ = 8cm x 5cm x Height

To find the height, we can rearrange the equation:

Height = 120cm³ / (8cm x 5cm)

Now, we can calculate the height using the given values:

Height = 120cm³ / (40cm²)

Height = 3cm

Therefore, the height of the room is 3cm.
