Find the height of a square pyramid that has a volume of 32 cubic feet and a base length of 4 feet

Mathematics

The volume of a square pyramid is found by multiplying the area of the base by the height divided by 3.

32 = 4^2 x h/3

32 = 16 x h/3

Multiply both sides by 3

96 = 16 x h

Divide both sides by 16

H = 96/16

H = 6

The height is 6 feet

Answer:

6 ft

Step-by-step explanation:

Volume of the pyramid:

  • V= lwh/3, where l- base length, w- base width, h- height

<u>Given</u>

  • V= 32 ft³
  • l=w= 4 ft
  • h=?

<u>Then, as per formula, we can solve it for h:</u>

  • 32= 4×4×h/3
  • h= 32×3/16
  • h= 6 ft

<u>Height of the pyramid is </u><u>6 ft</u>

n is initial population

t is time

since it doubles every second hour, and there are 6 hours

6hours/2hours= doubles 3 times, thats why t=3.

The length of a photograph is 3cm less than twice the width. The area is 54cm^2. Find the dimensions of the photograph.
REY [17]
W= width
l= length= 2w-3

Area= length * width
A= lw
substitute l=2w-3 for l
54= (2w-3)(w)
54= 2w^2 - 3w
subtract 54 from both sides
0= 2w^2 - 3w - 54
factor the polynomial
0= (2w + 9)(w - 6)

Set each set of parentheses equal
to 0 and solve for width.

0=2w+9
-9=2w
-4.5= w NEGATIVE VALUE

0=w-6
6 cm=w

-4.5 is not the answer because it has a negative value. You cannot have a negative side of a photograph. So substitute 6 in to find length.

length= 2w-3
l= 2(6)-3
l= 12-3
l= 9 cm

CHECK:
w= 6cm
l= 9cm
Area= length * width
54= 6*9
54= 54

ANSWER: width= 6cm; length= 9cm

Hope this helps! :)
