Question

Find the volume and surface area of the following cuboid
Length is 75cm
Breadth is 50 cm
Height is 1 m
Hint:
The formula of volume = length into breadth into height
The formula of area = 2[(length into breadth)+(length into height)+(breadth into height)]

Answer 1

Answer:

$\underline { Dimensions \:of \: a \:cuboid: }$

$Length (l) = 75 \:cm \\Breadth(b) = 50\:cm \\Height(h) = 1\:m = 100\:cm$

$i) Volume (V) = lbh \\= 75\:cm \times 50\:cm \times 100\:cm \\= 375000 \:cm^{3}$

$ii) Total \: surface \:area \\= 2(lb+bh+hl)\\= 2(75\times 50 + 50\times 100+ 100\times 75)\\= 2( 3750+5000+</p><p>7500)\\= 2\times 16250\\ = 32500 \:cm^{2}$
