The sum of the edges of a cuboid is 48 dm, the cuboid is known to be 8 dm long and 3 dm wide. The sum of the edges of a cuboid is 48 dm, and the cuboid is known to be 8 dm long and 3 dm wide.
48÷4-8-3,
=12-8-3,
=1(Decimeter);
Volume of cuboid:8×3×1=24(cubic decimeter);
Surface area of cuboid:(8×3+8×1+3×1)×2,
=(24+8+3)×2,
=35×2,
=70(Square decimeters);
Answer: Box volume is 24 cubic decimeters, surface area is 70 square decimeters.
