Answer:

The length is 22.5 and the width is 19.5

Step-by-step explanation:

2L + 2W = P

2L + 2W = 84

W + 3 + W + 3 + W + W= 84

4W + 6 = 84

4W = 78

W = 19.5 L = 19.5 + 3 = 22.5

55% of 1800 = 0.55(1800) = 990...so there are 990 girls in the school

30% of 990 = 0.30(990) = 297...so there are 297 girls who take the bus

The surface area of this rectangular prism is 34 square centimeters. What is the volume is the width is 1 cm, the length is 2 cm

Bezzdna [24]

Answer: $10\ cm^3$

Step-by-step explanation:

Given

The surface area of a rectangular prism is $34\ cm^2$

Width of prism $w=1\ cm$

Length of prism $l=2\ cm$

height of prism $h=x\ cm$

Surface area is given by

$S.A.=2[lw+wh+hl]$

Put values

$34=2[2\times 1+1\times x+2x]\\17=2+3x\\15=3x\\x=5\ cm$

Now, the volume of Prism is given by

$V=l\times w\times h$

$\Rightarrow V=2\times1\times 5=10\ cm^3$
