Question 1 - You need to split the L shape into 2 shapes.

6mm x 2mm = 12mm

and

5mm x 2mm = 10mm

add 12mm and 10mm
the area is 22mm squared (a little 2 above the mm)

question 2 - you need to do the same

4mm x 2mm = 8mm squared
7mm x 2mm = 14mm squared
area - 22mm squared

Answer:

Step-by-step explanation:

The volume of the regular pyramid is $V=\dfrac{1}{3}A_{base}H.$

The base of given pyramid is regular hexagon with side 12 cm. The are of this hexagon consistsof area of 6 equilateral triangles and is equal to

$A_{base}=6\cdot \dfrac{1}{2}\cdot 12\cdot 10.4=374.4\ cm^2.$

Hence, the volume of the pyramid is

$V=\dfrac{1}{3}\cdot 374.4\cdot 36=4,492.8\ cm^3.$

Answer:

1 pound- $4.7
2 pounds- $9.4
3 pounds- $14.1
4 pounds- $18.8

Step-by-step explanation:

Just hardware's prices are 0.30 greater per pound, so the equation would be y=4.7x. Substitute x in for each of the values to get the prices above.
