Find the total surface area of the triangle prism in the figure

Step-by-step explanation:

4 x 6 = 24 (side1)

8 x 4 = 32 (side2)

6 × 8 = 24 (side3)

6 x 8 = 24 (side4)

4 x 10 = 40 (side5)

surface area = 24 + 32 + 24 + 24 + 40 = 144ft squared

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
