Can someone me asap? it’s surface area

189 yd²

Step-by-step explanation:

Should be easy enough: Assume it's a rectangle solid and divide by 2.

l = 15 yd

w = 3 yd

h = 8 yd

d = 17.2627 yd

S = 378 yd² divide by 2 = 189 yd²

V = 360 yd³

Agenda:

l = length

w = width

h = height

d = diagonal

S = surface area  

V = volume

do your own work and don"t cheat.

step-by-step explanation:

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
