Answer:
yes
Step-by-step explanation:
the FIRST derivative of a function tells us the slope of a tangent line to the curve at any point. if is positive, then the curve must be increasing. If is negative, then the curve must be decreasing.
the SECOND derivative gives us the slope of the slope function (in other words how fast the slope of the original function changes, and if it is accelerating up - positive - or if it is avengers down - negative).
so, the first derivative would be fully sufficient to get the answer of if the slope of the function at that point is positive or negative.
but because it is only a "if" condition and not a "if and only if" condition, the statement is still true.
there are enough cases, where the slope is positive, but the second derivative is not > 0 (usually = 0).
but if even the second derivative is positive, then, yes, the slope of the original function must be positive too.

Answer:
The cube with surface area of 0.3 sq. meters will exert more pressure.
Step-by-step explanation:
Pressure is given by 
Since mass(m) and acceleration (a) for both the cubes are equal and the area varies, we will have to base our answer on the area.
In the formula for pressure, we can see that Pressure and Area are inverse of each other <em><u>(given mass * acceleration is constant, in this case).</u></em>
So the cube that will exert more pressure is the one with less surface area <u><em>(pressure and area are inverse of each other).</em></u>
Hence the cube with surface area of 0.3 sq. meters will exert more pressure.
