6 minutes 4 pieces = 3 cuts x 2 minutes each = 6 minutes
Cut a round cake in eight equal sized wedge shaped pieces with four vertical cuts, then make one horizontal cut through the center of the cake to equal sixteen pieces.It's slightly more tricky if you are only allowed to cut the horizontal cross-section of the cake (treat the cake as a circle). In this case, first divide the cake with one cut (2 pieces), then cut it again so that it intersects the first cut (4 pieces), then cut it a third time so that it intersects both cuts previously made, at different points (7 pieces), then let the fourth cut intersect all three cuts so far at different points (11 pieces), and let the fifth and final cut intersect all four cuts at different points (16 pieces total).

It really depends how long you make the pieces. You are better off in keeping the pieces multiples of 5 or 10 so you can maximise the amount of equal pieces
1) One vertical cut in half.2) A second vertical cut at 90 degrees to the previous one. You should now have 4 equal pieces.3) Make a cut parallel to the table, halfway through the cake. Like you are slicing a bagel in half or a subway sandwich. Should now have 8 equal pieces.4) Eat one piece!
2 horizontal cuts and 3 vertical cuts OR 3 horizontal cuts and 2 vertical cuts
Each cut("line") increases the number of slices by a multiple of 2 (provided that each cut crosses the center of the pizza). So, 1 cut would make 2 pieces, 2 cuts would make 4 pieces and 3 cuts would make 8 pieces
The imaginary line that cuts the earth into two equal parts is called the equator. It is an imaginary circle around the Earth that is equidistant from the North and South poles. It divides the Earth into the Northern Hemisphere and the Southern Hemisphere.
6 minutes 4 pieces = 3 cuts x 2 minutes each = 6 minutes
Cut a pizza into 2 using one straight cut. Stack the pieces and make a straight cut: you now have 22 = 4 pieces from 2 cuts. Stack these and make a straight cut: you now have 23 = 8 pieces from 3 cuts. Continue. After 7 cuts you can have 27 = 128 pieces. You can reduce the number of pieces to 29 if, after the fourth cut, you stack and cut only 11 pieces and thereafter cut just one each time. There are other options which give the same result.

yes. 1/2 is bigger than 1/4 because if you got 2 pizzas of the same size and cut one in 2 equal pieces and you cut the other in 4 equal pieces, the pizza with 2 equal pieces would have larger pieces than the pizza with 4 equal pieces. do you understand? i hope i helped. ☺
-- Adjust the direction of the knife so that it's parallel to the length of the cake,and cut (1) the cake down the middle ... 2 equal pieces.-- Turn the knife 90 degrees so that it's parallel to the width of the cake,and cut (2) the cake down the middle ... 4 equal pieces.-- Stack the 4 equal pieces in an even stack, so that their edges all line up.Cut (3) the stack in two equal pieces, either length-wise, width-wise, oralong either diagonal ... 8 equal pieces.Alternate method for any one of the cuts described above, (1) or (2) or (3):-- Turn the knife so that the blade is parallel to the cake-board and half ofthe height of the cake above the board. Slice through the height of the cake,keeping the knife parallel to the cake's bottom surface, to its top surface andto the cake-board, cutting the whole cake into an upper layer and a lower layerof equal thickness.
You can cut a cake into 16 pieces with 5 cuts by first making a cross-shaped cut dividing the cake into four equal pieces, then cut each of the four pieces in half horizontally and vertically with the last cut.
Cut the cake down the center once. Then cut it down the center again at a perpendicular angle from the first cut. Now you have 4 equal size and shape pieces. Take the pieces and line them all up in a row with each center angle point touching the center of the arc of the next slice of cake. Then cut down the center of each piece in one long continuous cut. There you have it. 8 equal size and shape pieces.
