Volume of space inside shop is 288 m³
<u>Given that;</u>
Dimensions of rectangle = 8 meter , 12 meter , 3 meter
<u>Find:</u>
Volume of space inside shop
<u>Computation:</u>
Volume of rectangle = [l][b][h]
Volume of rectangle = Volume of space inside shop
So,
Volume of space inside shop = [8][12][3]
Volume of space inside shop = [96][3]
Volume of space inside shop = 288 m³
