top. Ignoring the thickness of the plastic sheet, determine:
0 The area of the sheet required for making the box.
foret for it ifache​

Answer 1

Answer:

(l*b*h)-(l*b) apply this formula

Step-by-step explanation:

(1.5*1.25*65)-(1.5*1.25)

Answer 2

☘️ Given :

• Length = 1.5 m
• breadth = 1.25 m
• Height = 65 cm = 65/100 = 0.65 m

☘️ Solution :

So,

Area = CSA + area of base

= 2(l + b) × h + l × b

= 2(1.5 + 2.5) × 0.65 + 1.5 × 1.25

= 5.50 × 0.65 + 1.875

= 3.5750 + 1.875

= 5.45 m²

☘️ Answer :

• The area of the sheet required for making the box = 5.45 m²
