The 4th one to board can be any one of the remaining 4. For each of them ...
The 5th one to board can be any one of the remaining 3. For each of them ...
The 6th one to board can be either of the remaining 2. For each of them ...
The 7th one to board is the last 1 standing.
The number of different ways that this could play out is
(7 x 6 x 5 x 4 x 3 x 2 x 1) = <em>5,040</em>
14.3%
difference/actual = (3.2 - 2.8)/2.8 x 100% = 14.3% (3sf)

Answer:
6500 rupees
Step-by-step explanation:
We are given a rectangular garden is the dimensions of:
Length = 400 m
Breadth = 150 m
Perimeter of a rectangle = 2(L + B)
= 2(400 + 150)
= 2(650)
= 1300m
We are told that the cost of fencing a rectangular garden per meter is rupees 5
1 m = 5 rupees
1300m =
Hence, the cost to fence the entire garden = 1300 × 5 rupees
= 6500rupees
First, we know that the cubes are identical, therefore, they would have half the combined volume.
Each cubes's individual volume is 250/2 = 125 cubic cm
Since we know that this shape is a cube, we also know that all the dimensions of a cube are equal.
v=s³ where v is the volume and s is the side length
125 cubic cm=s³
∛125=s
5 cm=s
One of the cube's edge dimensions would be 5 cm.
Hope I helped :)
