Question

The external dimensions of a closed wooden box are 25 cm, 23 cm and 18 cm. If the thickness of the
wood used is 2 cm, find
(i) the total inner surface area of the box​

Answer 1

Answer:

You answer would be : 7728 $cm^2$

Step-by-step explanation:

Given:

Length = 25 cm

Breadth = 23 cm

Height = 18 cm

Because the cuboid is 2 cm thick, the internal length, breadth and height respectively would be:

Length = 23 cm

Breadth = 21 cm

Height = 16 cm

We know that the formula for surface area of a cuboid is {2(LB + BH + HL)}

Thus, TSA = 23 X 21 X 16 = 7728 $cm^2$

Hope it helps!

Answer 2

Answer:

Given:

Length = 25 cm

Breadth = 23 cm

Height = 18 cm

Because the cuboid is 2 cm thick, the internal length, breadth and height respectively would be:

Length = 23 cm

Breadth = 21 cm

Height = 16 cm

We know that the formula for surface area of a cuboid is {2(LB + BH + HL)}

Thus, TSA = 23 X 21 X 16 = 7728 cm^2
