Answer:

Total surface area of cuboid = 174 meter²

Explanation:

Given:

Length of cuboid = 9 meter

Width of cuboid = 5 meter

Height of cuboid = 3 meter

Find:

Total surface area of cuboid

Computation:

Total surface area of cuboid = 2[lb + bh + hl]

Total surface area of cuboid = 2[(9)(5) + (5)(3) + (3)(9)]

Total surface area of cuboid = 2[45 + 15 + 27]

Total surface area of cuboid = 2[87]

Total surface area of cuboid = 174 meter²

A tank containing diesel fuel(SG = 0.8) is open to the atmosphere at the top. A U-tube manometer is connected to the bottom of t

stepan [7]

Answer:

h= 37.9 m

Explanation:

Given that

SG = 0.8 for fuel so density of fluid will be 800 kg/m³.

We know that SG = 13.6 For Hg so density will be 13600 kg/m³.

Now by balancing the pressure

$\rho_d\times g\times h +\rho_d\times g\times 1.2 =\rho_{hg}\times g\times 2.3$

$800\times 9.81\times h+ 800\times 9.81\times 1.2 =13600\times 9.81\times 2.3$

$800\times 9.81\times h =13600\times 9.81\times 2.3-800\times 9.81\times 1.2$

$h=\dfrac{297439.2}{800\times 9.81}$

h= 37.9 m
