The height and base dimensions of a pyramid are shown in the diagram.

marusya05 [52]

Volume of the pyramid = 40 cubic units

Solution:

Let us find the volume of the pyramid.

Area of the base = $\frac{1}{2}\ bh$

$$=\frac{1}{2}\times4\times5$

= 10 square units

Area of the base (B) = 20 square units

Height of the pyramid = 12

Volume of the pyramid = $\frac{1}{3}\times \text{Base}\times \text{Height}$

$$=\frac{1}{3}\times 10\times12$

$= 40$ cubic units

Volume of the pyramid = 40 cubic units

What are two ways to find the difference 13/50 - 4.93

PtichkaEL [24]

Answer:

Find the two ways to find the difference of : $\frac{13}{50} -4.93$

First way:

$\frac{13}{50}$

To convert this fraction into decimal.

We have to make the denominator 100.

i.,e

$\frac{13}{50} = \frac{13 \times 2}{50 \times 2}= \frac{26}{100} = 0.26$

now,

$0.26-4.93 = - 4.67$

Second way:

Convert $\frac{13}{50}$ to $\frac{26}{100}$ and 4.93 to $\frac{493}{100}$ ,

Now:

$\frac{26}{100}-\frac{493}{100} = \frac{26-493}{100} =-\frac{467}{100} = -4.67$
