Answer 2

Answer:

the area of the cardboard required to make a closed box with the given dimensions =9120cm²

Step-by-step explanation:

Given:-

a closed box with the given dimensions:lenght=70 cm,breadth=40 cm and height=16 cm.

To find:-

Find the area of the cardboard required to make a closed box.

Solution:-

given dimensions:lenght=70 cm,breadth=40 cm and height=16 cm.

Let The length of the box(l)=70 cm

The breadth of the box(b)=40cm

The height of the box (h)=16cm

Using Concept:-

The area of the cardboard required to make a closed box is the total area of the cuboid

Using formula:-

Total surface area of the cuboid=2(lb+bh+hl) sq units

=>TSA=2[(70×40)+(40×16)+(16×70)] cm²

=>TSA=2(2800+640+1120) cm²

=>TSA=2(4560)cm²

=>TSA=9120cm²

Answer:-

the area of the cardboard required to make a closed box with the given dimensions =9120cm²
