Question

The length breadth and height of a cuboid tank oc 7m 6m and 5m respective find its volume find total surface area

Answer 1

SOLUTION

GIVEN

The length breadth and height of a cuboid tank is 7m 6m and 5m respectively

TO DETERMINE

The volume and total surface area

FORMULA TO BE IMPLEMENTED

If for a cuboid

Length = L , breadth = B and height = H

Then volume = LBH

Total surface area = 2( LB + BH + LH )

EVALUATION

Here it is given that the length breadth and height of a cuboid tank is 7m , 6m and 5m respectively

Length = L = 7 m

Breadth = 6 m

Height = 5 m

So volume

$\sf{ = (7 \times 6 \times 5) \: \: {cm}^{3} }$

$\sf{ = 210 \: \: {cm}^{3} }$

Total surface area

$\sf{ = 2 \times (7 \times 6 + 7 \times 5 + 6 \times 5)} \: \: \: {cm}^{2}$

$\sf{ = 2 \times (42 + 35 + 30)} \: \: \: {cm}^{2}$

$\sf{ = 2 \times 107} \: \: \: {cm}^{2}$

$\sf{ = 214} \: \: \: {cm}^{2}$
