Answer 1

Answer:

Given :-

Length = 8 cm

Breadth = 7.5 cm

Height = 12 cm

To Find :-

Volume

Total surface area

Solution :-

Firstly let's find its volume

\boxed { \bf Volume \: = l \times b \times h}

Volume=l×b×h

\sf {:} \implies \: Volume = 8 \times7.5 \times 12:⟹Volume=8×7.5×12

\sf {:} \implies \: Volume \: = 60 \times 12:⟹Volume=60×12

\huge \bf Volume = 720 \: cmVolume=720cm

Now,

Let's find TSA

\boxed { \bf TSA \: = 2(lb + bh + lh)}

TSA=2(lb+bh+lh)

\sf \: TSA\: = 2(8 \times 7.5 + 7.5 \times 12 + 8 \times 12)TSA=2(8×7.5+7.5×12+8×12)

\sf \: TSA = 2(60 + 90 + 96)TSA=2(60+90+96)

\sf \: TSA \: = 2(246)TSA=2(246)

\sf \: TSA = 492 \: cm {}^{3}TSA=492cm

3

Hence :-

Volume of cuboid is 720 cm and surface area is 492 cm.
