Arectangular box of length 40cm, breadth 25cm, and height 20cm is to be made out of tin what is the area of the tin sheet required if the box doesn't have a lid?

The answer to your question is: 3600 cm ²

Step-by-step explanation:

Rectangular box:

length = 40 cm

breadth = 25

height = 20 cm

Area =

Area of the base = 40 x 25 = 1000 cm²

Area of the lateral sides = 2(40 x 20) = 1600 cm²

Area of the sides = 2(25 x 20) = 1000 cm²

Total area = 1000 + 1600 + 1000 = 3600 cm²

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
