A cuboid has the dimensions as shown in the following diagram find its: (I) Volume. (II) total surface area. (III) area of four walls About the author Arianna
Answer ⇒ Length of a cuboid (l)=8cm ⇒ Breadth of a cuboid (b)=7cm ⇒ Height of a cuboid (h)=4cm ⇒ Total surface area of cuboid =2(lb+bh+hl) =2(8×7+7×4+4×8) =2(56+28+32) =2(116) =232cm 2 ∴ Total surface area of cuboid =232cm 2 Reply
Answer
⇒ Length of a cuboid (l)=8cm
⇒ Breadth of a cuboid (b)=7cm
⇒ Height of a cuboid (h)=4cm
⇒ Total surface area of cuboid =2(lb+bh+hl)
=2(8×7+7×4+4×8)
=2(56+28+32)
=2(116)
=232cm
2
∴ Total surface area of cuboid =232cm
