240 students
Step-by-step explanation:
Grade 7 : Grade 8 = 5 : 3
Number of seventh grade students = 5x
Number of Eighth grade students = 3x
3x = 90
x = 90÷3
x = 30
Total students = 5x + 3x = 8x = 8 * 30 = 240
Surface area= 2×(0.5bh)+4×8+4×8+4×square root of 2×8
=16+32+32+32root2
=80+32root2 square yards
Volume= Area of the base×height
=8×8
=64 cubic yards

Answer:
26 kg
Step-by-step explanation:
Jim has 19,700 grams of sand.
He brings home another 6,300 grams from the beach.
Total Weight of Sand in his sandbox=19700+6300=26000 grams
However, we are required to find how many kilograms of sand Jim have in his sandbox now.

26000 grams =
kilograms =26 kg
Jim has 26 kilograms of sand in his sandbox.
