 Hi friends and how are you all? The question says, find the cost of digging a cuboidal pit 8 meter long, 6 meter broad and 3 meter deep at the rate of rupees 30 per meter cube. So with the help of the cost, the rate of the cost which is given to us, we can get an idea that we need to find out the volume of this cuboidal pit first because volume is the only measure that is found out in cube. Here the length is given to us as 8 meters, breadth is given to us as 6 meters whereas the height is given to us as 3 meters. With the help of the knowledge of the formula of the volume of a cuboid, we can find out the volume of a cuboidal pit that will be length into breadth into height 8 into 6 into 3 that is further equal to 144 meter cube. So the cost will be equal to volume into rate that is further equal to volume is 144 meter cube into rate is rupees 30 per meter cube that will give us 144 into rupees 30 that is rupees 4 3 2 0. So this is our required answer to the session. Hope you understood the concept well and have a nice day.
