Plz only answer if u know the correct answer and get points

To calculate the volume of a cuboid (the shape shown) you need 3 values:

Width, length and height.

As we already have the width and length, we need the height and we can determine the height from the picture of the shape that is shown. In this case the height would be either RU or ST. We look at the possible answers to see if any of the possible answers match our possible solutions - in this case ST.

Therefore the answer would be a) ST

step-by-step explanation: i just don't

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
