The total surface area of a regular pyramid is the sum of the areas of its lateral faces and its base.
The area of the faces = four times the area of the triangle
= 4 * ( 0.5 * height * base )
= 4 * ( 0.5 * 8 * 15 ) = 240
The area of the base = area of a square
= 8 * 8 = 64

So, the total area = 240 + 64 = 304 sq. units

What is the product of Three-fourths and Negative StartFraction 6 over 7 EndFraction? -9/14

Brums [2.3K]

Answer:

The product is : $-\frac{9}{14}$

Step-by-step explanation:

First term given to us is = $\frac{3}{4}$

Second term given to us = $-\frac{6}{7}$

We have to find product for term 1 and term 2

Which means that we have to find : $(\frac{3}{4})\cdot(-\frac{6}{7})$

Calculating the product of fraction is pretty simple. To calculate the product of any two fractions. We have to multiple the numerator of 1st term with numerator of 2nd which serves as the the numerator of the product. Similarly we have to multiply denominator with denominator.

$(\frac{3}{4})\cdot(-\frac{6}{7}) = \frac{3\cdot(-6)}{4\cdot7} = -\frac{18}{28}$

Reduce the fraction

$-\frac{18}{28}= -\frac{9}{14}$
