Answer:
(0,-1,2,5)
Step-by-step explanation:

An appropriate measure for ∠CDE would be
∠CDE = ∠ADE - ∠ADC
<h3>How to check for the appropriate measure of CDE.</h3>
we have the following angles as parallel BC¯, DE¯, and FG¯ also CD¯, EF¯, and GH¯.
The angles that we have to check in order to measure would be
∠ABC, ∠AEG, ∠ADC, ∠AHG, ∠ADE, ∠AFE, ∠AHG.

Answer:
210
Step-by-step explanation:
Step 1: 6 rows and 6 columns each side so 6*6=36
Step 2: we have 6 sides so 36*6=216 cubes
Step 3: substract 6 cubes from the total since each row and column shares the same cube 216-6=210 cubes
The two trianglular faces we see have area
(1/2)(18)(14.1) and (1/2)(10)(16)
There's two more like these we can't see.
And the base has area
(18)(10)
for a total area of
A = (18)(10) + 2 ( (1/2)(18)(14.1) + (1/2)(10)(16))
A = 593.8
