Answers
Answer:The cost of wood required to make the box is 9150 rupees.
Step-by-step explanation:
Given, the outer dimensions of a closed wooden box are 22cm,15cm and 10cm.
∴The volume of the box = 22×15×10 cm³
= 3300 cm³
∵Thickness of the wood is 1cm.
∴The inner dimensions of the closed wooden box are (22-2)=20cm,(15-2)=13cm and (10-2)=8cm.
∴The inner volume of the box = 20×13×8 cm³
= 2080 cm³
∴The volume of the wood of the box = (3300-2080) cm³
= 1220 cm³
If,1cm³ of wood costs rupees 7.50
Then,the cost of wood required to make the box = 1220×7.50 rupees
= 9150 rupees
