So the "sum" means to add all of the terms: 1³ + 2³ + 3³
1³ is simply 1
2³ is 8
3³ is 27
so, from there, you just add all of those terms: 1 + 8 + 27 = 36
The first answer I have to just guess.
Step-by-step explanation:
Answer:23 cm
Step-by-step explanation:
Because it would equal the same amount because there are 10 mm in a cm
Answer:
a = 4 cm
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
a² + 3² = 5²
a² + 9 = 25 ( subtract 9 from both sides )
a² = 16 ( take the square root of both sides )
a = 
= 4
Answer:
Answer choice d
Step-by-step explanation:
To find the volume of this triangular prism, you first need to find the area of the triangular base. The formula for the area of a triangle is bh/2, which in this case is 3*2/2=3 square units. Multiplying this by the height of the prism, 3.5, you get a total of 10.5 cubic inches, or answer choice d. Hope this helps!
