Answer:
A) Vol_10_cubes  = 2*(5^4) inch^3
B) Area_10_cubes = (2^2)*3*(5^3)  inch^2
Step-by-step explanation:
A)The volume of a cube, as all sides are equal:
Vol_cube = (side)^3
side = 5 inches
Vol_cube  = 5^3 inch^3
Since we have 10 cubes
10 = 2*5
Vol_10_cubes  = 2*(5^4) inch^3
B) A cube has six faces, each with area equal to its squared side 
Area_cube = 6*(side)^2
Area_cube = 6*(5)^2  inch^2
Area_10_cubes = 2*5*6*(5)^2  inch^2
Area_10_cubes = (2^2)*3*(5)^3  inch^2
 
        
             
        
        
        
Answer:
 or
 or 
Step-by-step explanation:
Since a square's sides are all equal to each other  you can use this formula for  finding the area of a rectangle which is Base x Height or since all the sides are equal to each other you can just square the one side to get the desired answer!

Answer:
30 units
Step-by-step explanation:
if you count the boxes that each side takes up you get the first side being equal to 5 units and the base being equal to 12 units. because this is a right triangle to find the length of the hypotenuse you have to use the Pythagorean equation. when you input the values into the equation you get 5^2 + 12^2 = 169 which square roots to 13. after doing this you have the length of the final side, now input them into the formula for the perimeter of a triangle which is a + b + c and you get a perimeter of 30 units,
