Answer:
see below
Step-by-step explanation:
The area is given by
A = l*w
A = (4x-1) ( 3x+6)
FOIL
first 4x*3x =12x^2
outer 6*4x = 24x
inner -1*3x = -3x
last -1 *6 = -6
Add together
12x^2 +24x-3x-6
12x^2 +21x-6
To the nearest whole number it would be 35

Answer:
The surface area of the cube is 
Step-by-step explanation:
we know that
The length of a diagonal of a cube is equal to

where
b is the length side of a cube
In this problem we have

so

solve for b

Simplify

<em>Find the surface area of the cube</em>
The surface area of the cube is equal to

substitute the value of b
