And explain with the work that comes with it

V = l * w * h

l = 5 1/4

W = 3 1/2

H = 4

Notes

1. I've used 4/1 rather than 4 as one of the dimensions. 4/1 is easier to see

2. The 4s cancel in the first step. That makes both the numerator and denominator easier to read.]

3. In decimal form the answer is 73.5

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
