Robin made a cuboid of plasticine. Length, breadth, and height of the cuboid are 3 cm, 2 cm, 3 cm respectively. How many such cuboids will he need to make a
perfect cube?

it's very easy

we know that a cube will have equal sides

that is if the length of one side is ‘A’

then its dimensions are A*A*A

now we need to make a cube using 3*3*5 cuboids

since from the dimensions of the cuboid we have two different numbers, they are 3 and 5

now we need to find a least number which is a multiple of both numbers, for this we can multiply thise numbers so that we can get the least number which is a multiple of those two

3*5=15

now imagine int the following way

1)keep one the 3*3 faces in front of you, now the side of length 5 is perpendicular to your body surface

2)now clone up this cuboid one upon one so that the resultant height becomes 15, since we are stacking cuboids of dimensions 3*3*5 one upon one keeping 3*3 on your face, the resultant height will be a multiple of 3

=>n(1)*3=15

=>n(1)=5

so u need to clone the cuboid vertically 5 times

3)now the resulting 3d figure will be of dimensions 15*3*5, we got one side equal to 15,

now we need to get the other two sides equal to 15

4)for the second side, keeping 15*3 face in front of you clone it horizontally in a direction away from you, if you do this the length 5 will increase in multiples of 5,clone it till u get it equal to 15

=>n(2)*5=15

=>n(2)=3

so you need to clone it 3 times in your opposite direction

5)now you will be left with a new 3d figure of dimensions 15*3*15,

now clone this whole set so that 3’s will add up to become 15,

=>n(3)*3=15

=>n(3)=5

you need to clone it 5 times in the horizontal plane in the other direction leaving your opposite direction

now you will get a cube of dimensions 15*15*15

6)now how many times you cloned a single cuboid is

=> n(1)*n(2)*n(3) = 5*3*5 = 15*3 = 75

so you need 75 cuboids to make a cube.

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
