Question

find the area of the Cardboard required to make an open box of length 28cm, breadth 0.5m and height 0.2m.​

Answer 1

Answer:

Area of rectangle =(length+breadth) = 28+ 0.5 = 3.3=3square m

Answer 2

Answer:

Area of the cardboard required would be 0.592 m^2

Step-by-step explanation:

Area = 2lw + 2lh + 2hw

l = 28 cm = 0.28 m

w = 0.5 m

h = 0.2 m

Area = (2)(0.28)(0.5) + (2)(0.28)(0.2) + (2)(0.2)(0.5)

Area = (2)(0.14) + (2)(0.056) + (2)(0.1)

Area = 0.28 + 0.112 + 0.2

Area = 0.592 m^2
