John has 240 piece of sweet, His brother Stephen has twice of John's sweet and the Sister of John and Stephen has half of John sweet. what is the total sweets they all have altogether? 840 360 800 900

Step-by-step explanation:

No of pieces John has = 240

No of pieces Stephen has = twice of Johns sweet = 240 x 2 = 480

No of pieces John Sister has = half of John's sweet = 240 ÷ 2 = 120

Total sweets = 240 + 480 + 120 = 840

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "
