Question

Find the volume the lateral surface area and the total surface area of the cuboid whose dimensions are length 12cm breadth 8cm and height 45cm

Accepted Answer

ANSWER The area of only the curved part of a shape excluding its base is referred to as curved surface area s The total surface area includes the bases as well as the curving component It refers to the overall area covered by the objects surface The volume of an object or substance is the amount of space it takes up measured in cubic units It is given that length 12cm breadth 8cm and height 45cm We know that Volume of cuboid l b h By substituting the values we get Volume of cuboid 12 8 45 By multiplication Volume of cuboid 432 cm3 We know that Lateral surface area of a cuboid 2 l b h By substituting the values Lateral surface area of a cuboid 2 12 8 45 On further calculation Lateral surface area of a cuboid 2 20 45 By multiplication Lateral surface area of a cuboid 180cm2 We know that Total surface area of cuboid 2 lb bh lh By substituting the values Total surface area of cuboid 2 12 8 8 45 12 45 On further calculation Total surface area of cuboid 2 96 36 54 So we get Total surface area of cuboid 2 186 By multiplication Total surface area of cuboid 372 cm2
