Answer:
13.47 m
Step-by-step explanation:
let the angle formed by the shadow on ground be x
tan x = 1.65/(34.55-30 4)
tan x = .39
.39 = tree ht/34.55
tree ht = 13.47m
Answer: £40
Step-by-step explanation:
Answer:
2197 cm³
Step-by-step explanation:
surface area of cuboid = 2 * (5*9 + 33*9 + 33*5) = 1014
surface area of cube = 6 * x² .... x: side length of cube
6x² = 1014
x² = 169
x = 13
volume of cube = x³ = 13³ = 2197 cm³
