4.1 ≈ 4 inches (tenth place is less than 5, round down)
5.9 ≈ 6 inches (tenth place is more than 5, round up)
7.2 ≈ 7 inches (tenth place is less than 5, round down)
Volume = 4 x 6 x 7
Volume = 168 in³ (Answer C)
Hello, let's note A the matrix, we need to find 
such that A= I, where I is the identity matrix, so the determinant is 0, giving us the characteristic equation as
We just need to solve this equation using the discriminant.
And then the eigenvalues are.
To find the basis, we have to solve the system of equations.
