Answer:

120 cm^3;70 cm^3

Step-by-step explanation:

Volume = l * w * h

That means...

a) Volume = 12cm * 2cm * 5cm = 120 cm^3

b) Volume = 2.5cm * 8cm * 3.5cm = 70 cm^3

Answer:

a 120 cm^3

b 70 cm^3

Step-by-step explanation:

The volume of a right rectangular prism is given by

V = l*w*h

10 a  V = 12*2*5

          =120 cm^3

10 b V = 2.5 *8 *3.5

           =70 cm^3

What is the volume of a pyramid whose base is a square of area 36 and whose four faces are equilateral triangles?
irina1246 [14]

Answer:

V = 36\sqrt{2}

Step-by-step explanation:

The volume of a pyramid is

V = \dfrac{1}{3}Bh

where B = area of the base, and h = height of the pyramid

The base is a square.

A = s^2

s = \sqrt{A}

s = \sqrt{36}

s = 6

The side of the base has length 6. Each face of the pyramid is an equilateral triangle with side of length 6.

An altitude of this triangle measures

a = \sqrt{6^2 - 3^2}

a = \sqrt{27}

The pyramid is formed by 4 equilateral triangles whose bases form a square. The tips of the faces meet at a single point on top. The vertical distance from that point to the center of the base is the height of the pyramid.

h = \sqrt{(\sqrt{27})^2 - 3^2 }

h = \sqrt{27 - 9}

h = \sqrt{18}

h = 3 \sqrt{2}

Volume of the pyramid:

V = \dfrac{1}{3}Bh

V = \dfrac{1}{3}(36)(3\sqrt{2})

V = 36\sqrt{2}

The price of a shirt was $38. It was reduced by 20%. What was the price of the shirt after reduction.
kenny6666 [7]

Answer: $30.40

Step-by-step explanation: If you know that the original price is $38 and it was marked down by 20%, you could multiply the original price by ".80". This represents 80% of the original cost, since it was marked down by 20%. By multiplying $38 by .80, you end up with $30.40.

Hope this helps!
