Can someone help again please

192km^2

Step-by-step explanation:

Well there are 5 surfaces

1) The back one

10km*6km=60km^2

2) the square

(6km)^2=36km^2

3) the two triangles

2(6km*8km/2)=48km^2

4) the front one

6km*8km=48km^2

add all up and get

192km^2

192 square kilometers

Step-by-step explanation:

Two triangular Sides A=bh/2 8×6/2=24

So add two of them. : 48

Back side 10 × 6 = 60

Top 6×6=36

Front 6×8=48

Total: 48+60+36+48=192

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
