Find the surface area of the prism.

you multiply length times width of one surface like this:

8 times 3 = 24

then you multiply that by 4 because there are 4 sides with these measurements so 24 times 4 = 96

then you multiply 4 times 3 = 12 and multiply that my 2 because there are 2 sides with these measurements' so 12 times 2 = 24 then you add it all together

24 + 96 = 120

so the answer would be 120

Step-by-step explanation:

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

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.
