Answer 1

The suface area would he 188 becaaue u have to do 6x4 and then times that by 7

Answer 2

`\LARGE{ \underline{\underline{ \sf{\pink{ Required\: answer:}}}}}`

GIVEN -

• Water tank which is in a shape of right rectangular prism

Dimensions = 6 feet × 4 feet × 7 feet

TO FIND -

• Surface area of tank

SOLUTION -

Using formula of surface area of right rectangular prism -

Surface area =

`2(wl + hl + hw)`

L = length

w = width

h = height

( assumimg 6 feet = L , 4 feet = W , 7 feet = h)

Putting value of L, W and H in the equation. we get,

=2(4 × 6 + 7 × 6 + 7× 4)

= 2(24 + 42 + 28)

= 2( 94)

= 2 × 94

= 188
