A triangle has a height of 18 centimeters and a base of 3.5 centimeters. What is the area of the triangle?

31.5 cm^2

Step-by-step explanation:

The formula for the area of a triangle is 1/2 x (b x h)

in the provided question -

b = 3.5 cm

h = 18cm

The product the lies between__and__. 3×3/4?

Answers

Saying 3/4 * 3 is the same thing as saying 3/4 of 3. Imagine you have 3 pies, each cut into 4 slices. That would be 3 * 4 = 12 slices of pie, right?
So when there's 12 slices, that would be 4/4 of the pies, since all the pieces are there.
To find out how many pies we would have with 3/4 of the pie left, we just need to multiply the original equation.

3 * 3/4 = 2 1/4

The product of those two numbers lies between 2 and 3.
Hope that helped =)

Hello,
As each side of the display case is three times longer than the width of the artifact, the artifac is in the shape of a cube.
Let's the side of the artifac  be x.
The volume of the case is (3x)^3=3^3*x^3=27x^3
