Answer:
there are
16, 8, 12 and 4 different animals
Step-by-step explanation:
Step one:
given data
Number of Animals = 40
The given ratio is = 4:2:3:1
The total ratio is = 4+2+3+1= 810
Step two;
Applying the part to all method
The first animal
4/10=x/40
cross multiply
10x= 40*4
divide both sides by 10
x= 160/10
x= 16
for second we have
2/10=x/40
10x= 40*2
x= 80/10
x= 8
for the third we have
3/10=x/40
10x= 40*3
x= 120/10
x= 12
for the fourth we have
1/10=x/40
10x= 40*1
x= 40/10
x= 4

The formula for surface area is SA = 2lw + 2wh + 2lh
W = width
L= length
H = height
A = 2(wl + hl + hw)
2·(6·3+2·3+2·6)
Simplify that down to get the answer 72
