Question

Find the volume the lateral surface area and the total surface area of the cuboid whose dimensions are length 15m breadth 6m and height 5dm

Accepted Answer

ANSWER The area occupied by only the curved part of the shape omitting its base is referred to as the curved surface area s The total surface area includes the base s and the curving section It is the whole area covered by the objects surface The volume of an object or substance is the amount of space it takes up in cubic units It is given that length 15m breadth 6m and height 5dm 05m We know that Volume of cuboid l b h By substituting the values we get Volume of cuboid 15 6 05 By multiplication Volume of cuboid 45 m3 We know that Lateral surface area of a cuboid 2 l b h By substituting the values Lateral surface area of a cuboid 2 15 6 05 On further calculation Lateral surface area of a cuboid 2 21 05 By multiplication Lateral surface area of a cuboid 21 m2 We know that Total surface area of cuboid 2 lb bh lh By substituting the values Total surface area of cuboid 2 15 6 6 05 15 05 On further calculation Total surface area of cuboid 2 90 3 75 So we get Total surface area of cuboid 2 1005 By multiplication Total surface area of cuboid 201 m2
