A rectangular sheet of card board, shown below in Fig. - 1 is 26 cm long and 16 cm broad. Squares, each of 3 cm edge, has been removed from each corner of the paper sheet. An open cuboidal tray, as shown in Fig. - 2, was made using the remaining sheet of card board. What is the volume of the open space, in cubic cm. available in the tray? Correct Answer 600

Given

Length of cardboard = 26 cm

Breadth of cardboard = 16 cm

Formula Used

Volume of cuboid = length × breadth × height

Calculation

After removing squares of 3 cm from each corner,

Remaining Length = 26 - (3 + 3) = 20 cm

Remaining Breadth = 16 - (3 + 3) = 10 cm

So, Length of tray = 20 cm

Breadth of tray = 10 cm

Height of tray = 3 cm

Volume of tray = 20 × 10 × 3 

⇒ Volume of tray in cubic cm = 600

In the following question, the 1st and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/ passage is split into four parts and named P, Q, R and S. These four parts are not given in their proper order.
