Answer 1

Answer:

i) 1660.5 cubic units & ii) 1,084.5 square units

Step-by-step explanation:

i) Volume of a Cuboid = Length × Breadth × Height = 20.5 × 18 × 4.5 cubic units = 1660.5 cubic units

ii) Surface Area of a Cuboid = 2(Length × Breadth + Breadth × Height + Height × Length) = 2(20.5 × 18 + 18 × 4.5 + 4.5 × 20.5) square units = 1,084.5 square units

Volume of cuboid lbh

20.5*18*4.5= 1660.5 Answer

surface area =2(lb+bh+hl)

2(20.5*18+18*4.5+4.5*20.5)
