Answer:
I hope it is helpful
Step-by-step explanation:
length =12 cm breadth =10 cm height =5 cm
TSA=2(lb+bh+lh)=2[12×10+10×5+5×12]
TSA=2[120+50+60]=2×230
[TSA=460cm2]
(2) length =5 cm breadth =3.5 cm height =1.4 cm
TSA=2(lb+bh+lh)=2[5×3.5+3.5×14+1.4×5]
TSA=2[17.5+4.90+7.0]=2[29.4]
[TSA=58.8cm2]
(3) length =2.5 cm breadth =2 m height =2.4 m
TSA=2(lb+bh+lh)=2[0.025×2+2×2.4+2.4×0.025]
TSA=2[0.05+4.8+0.0600]=2[4.91]
(4) length =8 m breadth =5 m height =3.5 m
TSA=2(lb+bh+lh)=2[8×5+5×

Answer:
answer is 232
Step-by-step explanation:
l = 10 cm , breadth = 8 cm and height = 2 cm respectively. Now, TSA ( Total surface area ) of cuboid is 2 ( lb + bh + lh ). 2 ( 10 × 8 + 8 × 2 + 10 × 2 ). 2 ( 80 + 16 + 20 ) = 2 × 116 = 232.
