Answer:
A. 1/2x³
Step-by-step explanation:
Volume of the rectangular cube:
Area × lenght
Given ;
Width = x
Length = x
Height = 1/2 x²
Volume = width × length ×
= x × x × 1/2x
= 1/2x³
The correct answer is the first option.
Your intention with the wording "consecutive integers of 12 feet" is not clear. Shown are triangles with sides 12 and 13 (a nice Pythagorean triple) as well as 11 and 12.
There are several important information's already given in the question. Based on those given information's the answer to the question can be easily deduced.
Number of stamps that Ira has in his stamp album = 128
Number of pages that the stamp album has = 8
Then
Number of stamps in each page of the stamp album = 128/8
= 16
So 16 stamps are there on each page of the stamp album. I hope the procedure is clear enough for you to understand. You can always use this method for solving similar type of problems in future without requiring any additional help.
