Question

length 8.4 breadth 6.5and height is 4 find the volume and the surface area of a cuboid​

Answer 1

Answer:

218.4

Step-by-step explanation:

Formula for finding volume is V=L×B×H

Answer 2

Answer:

Volume= 218.4 m^3

Surface area= 228.4 m^2

Step-by-step explanation:

VOLUME

1. Volume of cuboid= l×b×h

V = (8.4×6.5×4)

V= 218.4

SURFACE AREA

Surface area of cuboid = 2( lb + bh + hl )

S.A = 2[( 8.4×6.5)+(6.5×4)+(4×8.4)]

.

. . S.A. = 2( 54.6 + 26 + 33.6)

S.A.= 2( 114.2 )

S.A.= 228.4
