The outer dimensions of a closed wooden box are 12cm by 10cm by 9cm.Thickness of wood is 1.5cm.Find the total wood required to make the box,if 1cmcube of wood costs ₹3.
Answers
Given outer length = 12 cm
Outer breadth = 10cm
Outer height = 9cm
Outer volume = length × breadth × height
= 12× 10x 9= 1080 cm3
Thickness of wooden box, w = 1.5cm
Inner length = l – 2w = 10 – 2 = 8 cm
Inner breadth = b – 2w = 8– 2 = 6 cm
Inner height = h – 2w = 12– 2 = 10 cm
Outer volume = 8 × 6 × 10= 480 c m3
Volume of wood used = outer volume – inner volume
= 560 – 240 = 320 cm3
Given cost of 1 cm3 of wood = Rs 2
Hence the total cost of wood required = Rs 2 × 320
= Rs 640

Answer:
Rs. 2736
Step-by-step explanation:
External dimensions of the wooden box are 12*10*9 cm^3
External dimensions of the wooden box are 12*10*9 cm^3Therefore, External volume= 12*10*9 cm^3 = 1080 cm^3
External dimensions of the wooden box are 12*10*9 cm^3Therefore, External volume= 12*10*9 cm^3 = 1080 cm^3Inner dimensions of the box are
External dimensions of the wooden box are 12*10*9 cm^3Therefore, External volume= 12*10*9 cm^3 = 1080 cm^3Inner dimensions of the box are 12- (1.5*2) = 9
External dimensions of the wooden box are 12*10*9 cm^3Therefore, External volume= 12*10*9 cm^3 = 1080 cm^3Inner dimensions of the box are 12- (1.5*2) = 910- (1.5*2)= 7
External dimensions of the wooden box are 12*10*9 cm^3Therefore, External volume= 12*10*9 cm^3 = 1080 cm^3Inner dimensions of the box are 12- (1.5*2) = 910- (1.5*2)= 79- (1.5*2)= 6
External dimensions of the wooden box are 12*10*9 cm^3Therefore, External volume= 12*10*9 cm^3 = 1080 cm^3Inner dimensions of the box are 12- (1.5*2) = 910- (1.5*2)= 79- (1.5*2)= 6Therefore, Inner volume= 9*7*6 cm^3= 168 cm^3
External dimensions of the wooden box are 12*10*9 cm^3Therefore, External volume= 12*10*9 cm^3 = 1080 cm^3Inner dimensions of the box are 12- (1.5*2) = 910- (1.5*2)= 79- (1.5*2)= 6Therefore, Inner volume= 9*7*6 cm^3= 168 cm^3Therefore, total volume of wood= (1080-168) cm^3 = 912 cm^3
External dimensions of the wooden box are 12*10*9 cm^3Therefore, External volume= 12*10*9 cm^3 = 1080 cm^3Inner dimensions of the box are 12- (1.5*2) = 910- (1.5*2)= 79- (1.5*2)= 6Therefore, Inner volume= 9*7*6 cm^3= 168 cm^3Therefore, total volume of wood= (1080-168) cm^3 = 912 cm^3Cost of 1 cm^3 of wood= Rs.3
External dimensions of the wooden box are 12*10*9 cm^3Therefore, External volume= 12*10*9 cm^3 = 1080 cm^3Inner dimensions of the box are 12- (1.5*2) = 910- (1.5*2)= 79- (1.5*2)= 6Therefore, Inner volume= 9*7*6 cm^3= 168 cm^3Therefore, total volume of wood= (1080-168) cm^3 = 912 cm^3Cost of 1 cm^3 of wood= Rs.3Therefore, total cost of wood= Rs. (912*3) = Rs. 2736
