Derive the cube class from the base square class. Assume the square class has a protected member variable representing the side called side and declared as a double with a default value of 1.0. It also has a public function called calcVal that evaluates the area of a square as side * side.

In your derived class have the default values for side be 1. For the cube class include a public function calcVal that evaluates the volume of the cube. (Hint: The volume of the cube is side * square :: calcVal.)

Attached solution 569148.cpp creates a base class Square, and derives class Cube from it as per the given specifications. It also ...

Solution Summary

Solution creates a base class 'Square' with protected member 'side'. It then derives class 'Cube' from it that makes use of 'side' from parent class, and also overrides 'calcVal' method of the parent class.

You had "2^(2/3) = 4^(1/3) = cube root of (4)"
It looks like you did 2^2 first and then did the 1/3 power. This is 100% correct. However, if we had a case where we had a perfect square or perfect cube, could we have take the denominator root first? Why?

When the accountants for lose-a-digit Computer, Inc. had finished preparing their annual budget, they presented the final figures to the president, I.M. Smart. "It looks like a good year," he exclaimed. "The amount of the budget just happens to be the smallest number of cents (other than one cent) that is a perfect square, a per

Surface area of a cube. The formula A = 6V^-2/3(-2/3 power) gives the
surface area of a cube in the volume V. What is the volume of a cube
with a surface area 12 square feet?
In addition please include the steps to solve for V if at all possible.

Eight small cubes are put together to form one large cube. All six sides of the larger cube are painted, the paint is allowed to dry, and then the cube is taken apart.
a) How many of the small cubes will have paint on just one side? On two sides, On three sides? On no sides?
b) Complete the following table, assuming in turn

2. The square root of x3 = 8
3. The square root of x2 = x an identity (true for all values of x)?
4. V = s3. Find the length of a side of a cube if the Volume is 729 cm3.
