You got the volume so the formula for finding a rectangular prism is l*w*h=x. l stands for length, w stands for width, h stand for height, and x stands for the total volume. Put the numbers in the formula so do 3*5*l=45 multiply the 3 and 5 and you will get 15*l=45 and divide by 15 on both sides (use a calculator if you can't do it in your head) and the answer should be 3.

Elan Coil [88]

Answer:

QV = 36 UNITS

Step-by-step explanation:

Centroid of a triangle divides the median in the ratio 2 : 1.

QU is the median and V is Centroid. Therefore,

QV : VU = 2 : 1

Let QV = 2x & VU = x

QV + VU = QU

2x + x = 54

3x = 54

x = 54/3

x = 18

QV = 2x = 2*18 = 36
