PLEASE HELP!!! The right rectangular prism is packed with unit cubes of the appropriate unit fraction edge lengths. Find the vol

never [62]

--------------------------------------------------
Formula :
--------------------------------------------------
Volume = Length x Width x Height

--------------------------------------------------
Find volume :
--------------------------------------------------
$\text { Volume = } 4\dfrac{1}{4} \times 5 \times 2$

--------------------------------------------------
Change to improper fractions :
--------------------------------------------------
$\text { Volume = } \dfrac{17}{4} \times \dfrac{5}{1} \times \dfrac{2}{1}$

--------------------------------------------------
Combine into single fraction :
--------------------------------------------------
$\text { Volume = } \dfrac{170}{4}$

--------------------------------------------------
Simplify:
--------------------------------------------------
$\text { Volume = } 42 \dfrac{1}{2} \ cm^3$

--------------------------------------------------
Answer: Volume = 42 1/2cm³ (Answer c)

The base of the pyramid is a square what is the surface area if the pyramids height is 4 feet in the area of the base is 36 ft.?

KATRIN_1 [288]

Answer:

96 ft²

Step-by-step explanation:

The general formula for the surface area of a pyramid is:

SA = $\frac{1}{2}$ pl + B, were p = the perimeter of the base, l = the slant height and B = the area of the base

Since the area of the base is 36 ft², then each side is √36, or 6 ft. The perimeter is the sum of all the sides, so 6 x 4 = 24 ft.

Given the overall height of the pyramid is 4 feet, you can use the Pythagorean Theorem (a² + b² = c²) to find the slant height (hypotenuse) of the pyramid. Using 3 feet for 'a' and 4 feet for 'b':

3² + 4² = c² or 9 + 16 = 25

25 = c² or c = 5

SA = $\frac{1}{2}$ (24)(5) + 36

SA = 60 + 36 = 96 ft²
