Answer: T.S.A = 4512cm^2
volume = 18900cm^3
weight = 17.01 kg
Step-by-step explanation:
T.S.A of cuboid = 2(lb+bh+lh)
= 2(42x25 + 25x18 + 42x18)
=2(1050 + 450 + 756)
=2 x 2256
= 4512cm^2
to find weight, we've to find the volume of the ice cube
therefore, volume of a cuboid = lbh
=42 x 25 x 28
=18900cm^3
weight of 1cm^3 of ice = 0.9grams
therefore weight of 18900cm^3 of ice = 18900 x 0.9
= 17010 grams = 17.01kg

Answer:
50
Step-by-step explanation:
x = √30² - 18² = √576 = 24
tan A = 18/24 = 3/4
∠A = ∠B
tan B = tan A = 24 / y = 3 / 4
y = (24 x 4) / 3 = 32
Z = y + 18 = 32 + 18 = 50
Answer:
x=e³-5
Step-by-step explanation:
Solve the equation by rewriting in exponential form using the definition of a logarithm and simplifying.
