Answer:
13r²(2rs + 4r³ - 3s⁴)
Step-by-step explanation:
In equation 26r³s + 52r⁵ - 39r²s⁴;
The GCF of 26, 52, and 39 = 13
The GCF of r³, r⁵ and r² = r²
The GCF of s, (no "s"), and s⁴ = no "s" (Since one of the number doesn't have "s")
Now we can factor out 13r² from all three expressions;
26r³s + 52r⁵ - 39r²s⁴
=> <em>13r²(2rs) + 13r²(4r³) - 13r²(3s⁴)</em>
To factor it all together;
<u>13r²(2rs + 4r³ - 3s⁴)</u>
Hope this helps!
Square rooting because you have to find the inverse of the equation to solve
Answer:
Surface area:


Volume :

Neither:



Step-by-step explanation:
Surface area of the cuboid:
The Surface area of the cuboid = 2(lb) +2(bh) +2(hl)
Where
l =length of the cuboid
b = Breadth of the cuboid
h = height of the cuboid
So ,
The surface area will be
SA = 
SA = 
SA =
SA = 
SA = 432
Volumes of the cuboid:

Volume = 
volume = 576
