Answer:
Step-by-step explanation:
area of triangular face = ½·3·4 = 6 cm²
area of 3 by 7 face = 3×7 = 21 cm²
area of 5 by 7 face = 5×7 = 35 cm²
area of 4 by 7 face = 4×7 = 28 cm²
total surface area = 2×6 + 21 + 35 + 28 = 96 cm²
0.24 should be your answer

Answer:
Step-by-step explanation:
a + c = 92.....c = 92 - a
8a + 5c = 688
8a + 5(92 - a) = 688
8a + 460 - 5a = 688
3a = 688 - 460
3a = 228
a= 228/3
a = 76 <==== adults
a + c = 92
76 + c = 92
c = 92 - 76
c = 16 <=== children
