Answer:
Volume
Figure 1 = 56 cube units
figure 2 = 60 cube units
figure 3 =72 cube units
Surface area
Figure 1 = 100 square units
figure 2 = 104 square units
figure 3 =108 square units
Step-by-step explanation:
From the all figure we can see that each figure made up of unit cubes
Figure 1
Surface area
Large cuboid portion =2 x (6 x 2 ) + (6 x 4) + 2 x(4 x 2) + 16
= 24 + 24 + 16 + 16 = 80 unit square
Small cuboid portion = (4 x 2) + (2 x 2) + (4 x 2) = 8 + 4 + 8 = 20
Total surface area = 80 + 20 = 100 unit square
Volume
Small cuboid = 4 x 2 = 8
Large cuboid = 6 x 4 x 2 = 48 cube unit
Total volume = 48 + 8 = 56 cubs units
Figure 2
Surface area
Total surface area =24 + 18 + 36 + 20 + 6 = 104 unit square
Volume
Small cuboid = 6 x 2 = 12
Large cuboid = 6 x 4 x 2 = 48 unit square
Total volume = 48 + 12 = 60 cube units
Figure 3
Surface area
Total surface area = 48 + 36 + 24 = 108 square units
Volume
Total volume = 6 x 4 x 3 = 72 cube units

A hungry college student just finished eating a large cheese and pepperoni pizza from Doug's Pizza Palace and felt there wasn't enough cheese and pepperoni on it as he has had large pizzas with more cheese and pepperoni on it from this place in the past. This led him to wonder what the average weight of a large cheese and pepperoni pizza was at Doug's Pizza Palace. Doug ordered a large cheese and pepperoni pizza from Doug's Pizza Palace on 15 randomly selected days during a particular term and weighed each before eating it. Suppose all conditions are met for inference using the one-sample t-methods. The student constructed a 95% confidence interval for the population mean using the one-sample t-methods. How many degrees of freedom does the t critical value have?

3 feet
34 inches
5 feet
Answers
1 foot = 12 inches
4 feet 2 inches = 50 inches
4 feet 2 inches - 14 inches = 50 - 14 = 36 inches
36 inches = 3 feet
The correct result would be 3 feet.
3 ft. because 4 ft. converted to inches is 48 in. + 2 in. - 14 in. = 3 ft.

Answer:
AC = BD = 1 unit
Step-by-step explanation:
Given : length of diagonal of rectangle ABCD and
We have to find the length of diagonal.
We know In rectangle diagonal are of equal lengths.
Therefore, for rectangle ABCD diagonals AC= BD
Substitute the values, we get,
Cross multiply , we get
On simplyfy , we get
Solve for y , we get
Divide both side by 12, we get,
Thus, put the values of y in AC and BD to find the length of diagonals , we get,
Similarly for BC, we get,
Thus, AC = BD = 1 unit
