Answer:

Step-by-step explanation: View this in 3 dimensions, top, front, and right. Adding these 2d surface areas and multiplying by 2 will give the surface area of the entire figure. From the top, there are 6 squares, each square has 5in side length so the area of the total is 5^2 x 6 = 150. From the right, there are 3 squares for 5^2 x 3 = 75. From the front are 4 squares, so 5^2 x 4 =100. 2(100+150+75)= 650in

The required value is $2\times10^9$

Step-by-step explanation:

Weight of ants = $4\times10^{-3}$

Weight of elephant= $8\times10^6$

We need to find, the total weight of about how many ants equals to the weight of an oversized elephant.

The equation given is:

$4\times10^{-3} \times a = 8\times10^6$

We need to find a:

Solving:

$4\times10^{-3} \times a = 8\times10^6\\a=\frac{8\times10^6}{4\times10^{-3}}\\if \,\,10^a/10^-b \,\,then\,\, 10^{a+b}\\a=2\times10^{6+3} \\a=2\times10^9$

So, the required value is $2\times10^9$
