Susan made a block with small cubes of 8 cubic cm volume to make a block ,3 small cubes long, 9 small cubes wide and 5 small cubes deep. She realizes that she has used more small cubes than she really needed. She realized that she could have glued a fewer number of cubes together to lock like a block with same dimensions, if it were made hollow.

Planet fourfi resides in 4 dimensional space & thus the currency used by its residents are 3 dimensional objects.the rupee are cubical in shape while their coins are spherical.however the coin minting machinery lays out some stipulations on the size of the coins.
The diameter of the coins should be atleast 64mm & not exceed 512 mm.
given a coin,the diameter of the next larger coin is atleast 50% greater.
the diameter of the coin must always be an integer.
you are asked to design a set of coins of different diameters with these requirements & your goal is to design as many as coin as possible.how many coins can you design?
a)9 b)5 c)6 d)8
Anoop managed to draw 7 circles of equal radii with their centres on the diagonal of a square such that the two extreme circles touch two sides of the square and each middle circle touches two circles on either side. Find the ratio of the radius of the circles to the side of the square.(v belongs to root i.e v2 = 1.414)
a) 1:(4+ 7v3) b) 1:(2+ 6v2) c) 1:(2+ 7v2) d) (2+ 7v2):1
A Seamstress buys a certain amount of gringham cloth which comes in rolls that are exactly 56 inches wide. She also bought a certain length of Seersucker- 1 yard long and 35 inches wide. She discovers she has 112 yards of gringham and she wants to divide this into 112 lengths of 1 yard each. She wants to have twice as many pieces as Seersucker as she does of gringham. It takes her 8 seconds to cut each length working non stop, how long in seconds does it take to cut 112 pieces.
Planet fourfi resides in 4-dimensional space and thus the currency used by its residents are 3-dimensional objects. The rupee notes are cubical in shape while their coins are spherical. However the coin minting machinery lays out some stipulations on the size of the coins.
1)The diameter of the coins should be at least 64mm and not exceed 512mm.
2). Given a coin, the diameter of the next larger coin is at least 50% greater.
3). The diameter of the coin must always be an integer.
