Answer:
Surface area of the box is 13,034
Explanation:
To find the surface area, we can use the given expression:
{{Surface Area}} = 231(31-20) + 2((31+50)(31-20))+231+50) 31)
Let's solve it step by step.
Step 1: Simplify the expression inside the parentheses first.
31 - 20 = 11
31 + 50 = 81
Step 2: Substitute the simplified values back into the expression.
{{Surface Area}} = 231(11) + 2((81)(11))+231+50) 31)
Step 3: Perform the multiplications inside the parentheses.
231(11) = 2541
(81)(11) = 891
Step 4: Continue simplifying the expression.
Surface Area}} = 2541 + 2(891)+231+50) 31)
Step 5: Perform the multiplications outside the parentheses.
2(891) = 1782
(231+50) = 281
(281) 31) = 8711
Step 6: Substitute the results back into the expression.
{{Surface Area}} = 2541 + 1782 + 8711
Step 7: Add all the terms together.
{{Surface Area}} = 13034
Therefore, the surface area of the box is 13034.
