### Given 1000 small cubics, what is the length of the edge of the biggest cubic you can make.

you dont have to create the cube with unit cubes in the volume...you can have all of the cubes on the edges alone. The answer is the solution of the inequality. X^3-(X-2)^3 &lt;1000 Less

13

shouldn't be 10? how do you get the value 13/83, can you explain a bit?

### Why do you want to come to Singapore?

In order to fulfil the work seismic imaging processing given by the company in that area and also to meet the requirements of the company. Less

### What is the area of a 16 sided regular polygon with sides of length L ?

Area of a regular polygon A = 1/4 *n*l^2*cot(pi/n) Where n is the number of sides = 16, l is the length of a side = L Therefore A = 1/4*16*L^2 * cot(pi/16) = 20.10*L^2. Less

area = L^2/tan(2*pi/32) ~= 5*L^2

area = 16*(L^2/tan(2*pi/32)/2) ~= 40*L^2

### What do you know about CGG?

How do you handle stress?

could you tell me some technical questions they asked?

### Suppose you have a M x N mesh grid, how many rectangulars could you draw? Could you write a code to find the prime numbers from 1 to N?

Additional information for the first one: There are N by 1 grid, there are N 1 by 1 rectangles, (N-1) 2 by 1 rectangles, ..., 1 N by 1 rectangles. Total # = N(N+1)/2. For N by M grid, total # = N(N+1)/2 * M(M+1)/2. Less

Just for the first one, if M and N represents the size, my answer would be (M+1)*M*(N+1)*N/4 Less

Explained how I allowed myself to get busy in college with some extra-curriculars but was sure to do grade replacements. It's ok to falter at some points in life, you just have to pick yourself up and make sure you fix things and take care of your business. Less
