SO you would have to first have the surface area of the cube which is 25 for each side so 25 x 6 = 150
Then you find the surface area for the other sides and It is 4 x 5 divided by two for each triangle on the side, so that would be 20 and you multiply then 6.4 x 5 to equal 32 for the rectangle. The last part is the bottom and it is 4 x 5 again which is 20 so then you add them all up but im not sure.
Answer:
<h2>
a₁₈ = - 31</h2>
Step-by-step explanation:

Solution we have
The triangular prism in which
Let Sp = 16., S2 = 10,83 = 10 Now, L=
12 cm
then, we know that,
lateral surface area of
Triangular prism = L (S, +S, +S2)
= (16+10+10)/12)
Hence, the correct. option A is correct
X 1 2 3 4
p(x) 0.40 0.20 0.15 ?
If the items are only 4. The total of the probability must be 1 or 100%
1 - 0.40 - 0.20 - 0.15 = 0.25
The probability of 4 is 0.25.
