Question

A plastic box 2m long 3m wide and 5m deep into be made . it is opened at the top.. ignoring the thickness of the plastic sheet determine area of the sheet required making the box​

Answer 1

Answer:

Step-by-step explanation:

area = Lateral + Base area

area= 2h(l+b) + lb

area = 2x5(5) + 2*3

area = 50+6

area=56m2

Answer 2

Amount  of area of the sheet required making the box​ is equal to 56 m²

Step-by-step explanation:

• Length of box (L) = 2 m

        Width of box(B) = 3 m

        Depth of box (D) = 5 m

• Area of top surface = Length× Width

        Area of top surface = 2× 3 =6 m²

• We know the formula of total surface area of cuboid for open box, which are given below

• Total surface area for open box (T.S.A) = 2×(L×B+B×H+L×H) - L×B

• Total surface area for open box (T.S.A) = 2×(2×3+3×5+2×5) - 2×3

• Total surface area for open box (T.S.A) = 2×(6+15+10) - 6

• Total surface area for open box (T.S.A) = 56 m²

• So amount  of area of the sheet required making the box​ is equal to 56 m².
