Answer:

125 meters squared

Step-by-step explanation:

Surface area of initial pyramid:

  • A= 10²+4*1/2*10*15= 400 m²

Surface area of extended pyramid:

  • A= 10*15+2*1/2*15*15+2*1/2*10*15= 525 m²

The difference is:

  • 525- 400= 125 m²

If represented in a stem and leaf plot, what would be the leaf of the number 329?​
sdas [7]

Answer:

You can either do a back to back stem and leaf plot, where you would have double the values. In a normal stem and leaf plot you would just have one set of 3's where you would put all the values that start with 3 in that column. A back to back is the same but instead you would have two 3 values, where anything that is higher than 5 would be in the second value of 3, but anything lower would be in that first value of 3.

Box A has a volume of 512 cubic meters. Box B is similar to box A. To create Box B, Box A's dimensions were divided by 2. What i
bearhunter [10]

Answer : The volume of box B is 64m^3

Step-by-step explanation :

Given :

Volume of box A = 512 cubic meter

Let us assumed that the box A and box B are cubes and the dimensions of cube are same i.e, 'a'.

Volume of box A = V = a\times a\times a=a^3

As per question,

When dimensions of box A divided by 2 then the volume of box B will be:

Volume of box A = V' = \frac{a}{2}\times \frac{a}{2}\times \frac{a}{2}=\frac{a^3}{8}

As the box B is similar to box A. So, the volume of box B will be:

Volume of box B = V' = \frac{a^3}{8}

V'=\frac{a^3}{8}=\frac{V}{8}

V'=\frac{512m^3}{8}=64m^3

Therefore, the volume of box B is 64m^3

Here, we shall be selecting the correct answer from the option.

a. A is correct

the number we want is between 2.4 and 2.8

2.5 is greater than 2.4 but less than 2.5, this means it meets our criteria

b. 2.41 is also correct

This is because it is greater than 2.4 but less then 2.8

c. wrong

2.4 is same as 2.4, it does not meet the criterion

d. wrong
