A building block has the dimensions height Xcm, width (3+X) cm, depth Xcm
What espression, in terms of x, would represent the total surface area (A) of the block? Put the expression into the simplest terms.
Draw a graph, estimate a value for x, which will give a surface area of 175.5 cm squared.
Check your extimate of x by solving the equation when A = 175.5© BrainMass Inc. brainmass.com November 24, 2022, 12:00 pm ad1c9bdddf
There are six sides to the block,
two sides have the area = depth * width (Note: "*" means multiply)
two sides ...
The expressions represented with graphs are provided. The total surface of the block is found.
