The volume of a pyramid is given as: 1/3 x base area x height.
= 1/3 (1/2 x 8 x 6)x 11
=1/3 ( 24)x11
= 8 x 11 = 88 cm^3
The answer is in the image
For every 8 cars there are 7 trucks
Therefore,
Cars:Truck=8:7
Answer is B)8:7
Salesperson will make 6% of 1800
=(6/100)*1800
=108
Salesperson will make $108 in $1800 sales
Speed=Distance/time
Here,
distance=15m
time=1sec
speed=15/1=15m/sec
Distance=Speed*time
time=15min=15*60sec=900sec
Distance travelled in 15 min=15*900=13,500m
=13500/1000 km=13.5Km
30% of 420 are first year students
first year students = (30/100 )*420
=126 students
Student who are not in first year = 420-126
=294 students
Area of rectangle= L*b
here,
L=12.4 cm
b= 8.8 cm
A= L*b
= 12.4 * 8.8 = 109.12 cm^2
Volume of pool = 1472 m^3
Length = 36.8m
Breadth = 20m
We know,
Volume = l*b*h
1472 = 36.8 * 20 * h
h = 1472/736
h = 2m
Pool is 2m deep
