Answer:
Total surface area of the prism = 920 cm²
Step-by-step explanation:
Given prism has 2 similar triangular surfaces and 3 rectangular surfaces of different dimensions.
Area of one triangular side = 
Area of 2 similar sides = Base × Height
= 8 × 15
= 120 cm²
Area of rectangular side with dimensions 17cm × 20cm
Area of the side = 17 × 20 = 340 cm²
Area of the second rectangular side with dimensions 8cm × 20cm
Area of the side = 8 × 20 = 160 cm²
Area of third rectangular side with dimensions 20cm × 15cm
Area of the side = 20 × 15 = 300 cm²
Total surface area of the given triangular prism = 120 + 340 + 160 + 300
= 920 cm²
Answer:
hope its correct and does helps u
I think the answer is shelter B
A = {0, 1, 2, 3}
C = {0, a, 2, b}
A ∩ C = {0, 2} → E)
A set of the same elements from the set A and the set C.
Answer:
Answer is 25/56
Step-by-step explanation:
Given that
Katie and her brother are both writing a report. Katie write 7/8 of her report and her brother wrote 3/7 of his report
TO compare these two fractions we have to make both of them have the same denominator.
We find that as such the two fractions have denominators as 7 and 8 and hence Least common multiple is 56
LEt us make equivalent fractions
7/8 = 49/56
3/7=24/56
Difference i.e. Katie wrote more than her brother = 49/56-24/56
=25/56
